A place for me to review the various rugged, nifty and needful kit that I've accumulated, for every-day preparedness in the event of accident, disaster or world-shifting end-times Apocalypse, be it zombies, triffids or Mayan divide-by-zero errors.

Review: Gearlex Ear Clip
I wanted to upgrade my accessory carrying capacity without adding my weight, or adding to my magnetic signature. (I rarely go through metal detectors, but whenever I do, it's a bigger and bigger pain each time). I use ITW Grimloc's on a bunch of my bags and harnesses, which are good, but have a "pop-open" thresh-hold that I have had come open at inopportune times.
I saw that Hornest SG was stocking a bioplastic carabiner that looked to be suiting my needs. These are the Gearlex Ear Carabiners. These weather and chemical resistant clips are made from 62% renewable materials and ends up being 15% lighter than nylon materials and are reported to retain that toughness down to -60oC, in case you are intending to go yomping in Vladivostok or Mawson Station.
At the broad top of the "ear" shapes, the clips feature a 1" webbing loop, with a split notch for feeding it into the location of your choice.
Unlike the webing notch of the of the Grimloc, the Gearlex webbing loop is on the outside of the carabiner, not the inside. This frees up the internal area of the carabiner to give more space for attached objects, and adds freedom of movement.
However, it makes me worry about how much of a load the clip can take. The large Ear clips are rated to a max of 78kg and the small to 60kg, which is vastly more than the Grimloc's 36kg break-point. I rather empirically tested it manually by pulling it looped through my webbing , and it held in place to the point of hurting my hand and with the stitching straining.
The gate of the carabiner is fitted with a dovetail locking mechanism which adds to the strength of the gate and is one of several locks now standard throughout the climbing world. The inside, weight bearing rim of the carabiner is thicker, to distribute the load, but the back edges have a broad rib for stability and strength, without adding too much mass.
The carabiners are clearly not climbing rated, and come with warnings not to be "load-bearing" but that said, for the strapping of accessories, like water bottles, dummy cords or even strapping on smaller packs to bigger packs, such as the Hill People Gear Runner's Bag, or the Zulu Nylon Gear CAOS admin pack or even perhaps a daypack, for those of us who pack like we're about to jump out of a perfectly good airplane.
Gearlex produce these in Black, Coyote and Ranger Green, and I got one of the clips in black, one in ranger green and a small one in Ranger Green as well, to give me some options when I am setting them up and using them, to match or contrast the gear they are attached to.
Not as hardy and load-bearing as an aluminium or steel climbing carabiner, bigger and more stable than a Grimloc, the Gearlex Ear Clips fill the niche between a light accessory clip and a heavy-duty carabiner.
Both have their places and uses, but for something in-between, you might find that the Gearlex clips, in big and small suits your needs.

Wish Lust: Anachrobellum war-outta-time shirts
I wanted to take a moment to give a shout out to the folks at www.anachrobellum.com who, in conjunction with the Knife-hand the World folks, have put some pretty stellar t-shirt designs together, incorporating some of my favourite things. Vikings, Samurai and Revolutionary War warfighters, fitted and kitted with modern wargear.
Here are the three shirts that are available now:
This is the Til Valhall shirt. It portrays what a modern Viking pipe-hitter might look like while servicing his enemies with cold steel and hot lead.
As you can see, this berserker is a little better equipped to wreak slaughter and carnage upon his foe than were his distant ancestors — though true to form he has transitioned from blaster to a bearded skull splitter to make a point. We’re pretty sure Gunnar Hamundarson and Egil Skallagrimsson would approve.
Sure, maybe they didn’t have frags and mags in the Fóstbræðra saga, but that’s the way Anachrobellum rolls…and for that matter, it’s the way most of you roll as you conquer your way to Valhöll.
Here is the second in their line, The Tactical Samurai.
Why the Samurai? Of all the warrior archetypes in the world, none is perhaps more recognizable than that of the Samurai. The word Samurai is derived at least in part from the word saburau, which means “to serve.” That’s fitting enough, particularly in the modern context and even more so with regard to how we regard the warrior ethos. There’s nothing wrong with a little ego in a fighting man, quite the contrary — but if that ego is not subordinated to some sense of the greater good (serving your country, serving your community, sticking up for those weaker than you), well, then…
This particular Samurai is carrying some things MInamoto Tametomo and Miyamoto Musashi wouldn’t recognize — Mk17, PEQ15, OSS Suppressor, S&S Precision Manta strobe and the like — but they’d understand the philosophy behind it.
Lastly, Roger's Rangers are back in the Roger's Rangers Returned shirt from . The frontiersmen and scouts trained by Robert Rogers were asymmetrical warfare experts before there even was a Continental Army (and long before anyone coined the term Asymmetrical Warfare). Once the Continental Army was established, its original 10 Rifle Companies were veterans of Roger's Rangers.
Capt. Robert Rogers first recruited his men in 1775 to support the British Army during the French and Indian War, conducting recce operations, raiding and essentially becoming an iconic example of (truly) light infantry operations.
This is a storied unit of American military history. Indeed, Rogers Rules of Ranging are studied and quoted even today -- just take a look at the United States Army Ranger Handbook, numerous scholarly works about warfare and counterinsurgency manuals. As such, Anachrobellum believes this warrior archetype to be imminently suitable for many of today's armed citizens and uniformed professionals.
The original Roger's Rangers were obviously limited in their equipment and weaponry. Those of today have far more impressive tools -- this is why our Roger's Ranger Returned is rocking SKD PIG gloves, a MK17 with Elcan Spector and PEQ15 -- as well as assorted other gear and the mandatory tomahawk of course!

Review: SAR GlobalTools - kiridashi
The traditional kiridashi knife is small and very portable blade from Japan, with a chisel grind and a sharp point, used as a general-purpose utility knife. These knives are carving/utility knives have their roots in woodworking. The name, kiridashi literally translates to “carve out” which would seem to support this origin. Regardless, they are found in many facets of traditional and contemporary Japanese culture being used in a variety of activities from everyday tasks like sharpening pencils to gardening.
They are often made with a handle wrap and sometimes scales and a scabbard, but are just as likely to be a single piece of steel.
This take on the classic is from my mate Spencer Alan Reiter of SAR Global Tools who works his metalworking magic from a shed in Louisiana and has brought forth such wonderful items as the Moonglow necklace signaling tool I wear 24/7, the SESS signalling dogtag I keep lashed to all my packs, and my favourite neck-knife, the OddJob.
The SAR kiridashi's are all one-offs, that Spencer builds from reclaimed stock left over from his other projects. Waste not, want not, and perfect philosophy for the creation of a kiridashi. The riddle of steel rings in his ears.
Crafted from an offcut of CPM3V and is heat treated to a hardness of "dead nuts" 60HRC according to Spencer.
It's also sharpened to a razor blade edge along both its main cutting edge and to a very sturdy and substantial point. The geometry of the SAR kiridashi is is very similar to a scalpel and being one piece CPM3V its 165mm length it weighs only 30g, very dense and very good in the hand. With two holes drilled in the head of the blade for a mass reducing effect and three grip-enhancing drilled notched behind the head, and another in the tail end as a lanyard hole.
Worked over in the SAR workshop, you can easily use it knowing that you are using a high quality product. You'd never know it was a one off recovered from workshop scrap. In keeping with the kiridashi's main purpose originally to be used as a craft knife, I wanted to show off it's practical application and the single, flat ground chisel edge which just works a treat as a wood whittling tool.
The blade can put it to many different uses. Here are some practical examples: general cutting, gardening, cutting zip ties, deburring and drilling holes, self defense, survival tool, the uses are almost innumerable. Anything you could want from a heavily over-engineered craft-knife.
The SAR kiridashi's are set with a cord-wrap on the handle for enhanced grip on the thin metal spine, and come with a kydex scabbard along with a bead-chain necklace for neck-knife wear.
Bear in mind that these are all hand-crafted, heat treated and sharpened in what is essentially a one-man shop, along with Spencer's philanthropic work in conjunction with the Run Rangers Run charity, in creating his Inglorious Bastards knives, re-purposed from antique files, so his time is hard to come by and the runs are small. Keep an eye out and be on the lookout for new knives such as the Kingfisher's that are coming out...

Review: Mystery Ranch - Removable Stick-it
I got in touch with my mate Tay Choon Mong at Hornest Singapore, my favourite stockist of the hardy and heavy-duty Mystery Ranch packs and products, after I saw that they had some accessories I had been hanging out for come in. You may recall I have one of the rare Mystery ranch "Asia Pacific only" 1 Day Assault Pack bags, which is a cross between the more mature 3 Day Assault Pack and the more recently released ASAP Pack.
I also have one of the Cinch straps, for comfortable wear and quick release of a pack whilst wearing a loaded plate carrier.
Great kit. The particular accessory that had come to my attention was the Removable Stick-It flap, seen here in Coyote, mounted to my black 1DAP. The Stick-It is a detachable beaver-tail that mounts to the bottom of a compatible pack to offer external storage when you've either gotten too much stuff, or just something too big for your pack to carry.
Built with 500D Cordura for long-haul durability, which I've come to expect from pack-makers, and fitted with mil-spec 1" webbing straps, Mystery Ranch have gone all out on the both the construction and the hardware. The buckles have a clip-in end, for fixing to MOLLE loops or other webbing on your pack, as well as a spring loaded friction lock for the working end of the buckle.
This kind of attention to detail as well as using better-than-standard fittings is something I love about Mystery Ranch. You pay for it, but it's worth it. The Stick-It attaches to its host pack with four press-stud closing loops of webbing, which feed back into the accessory by extra loops of MOLLE style webbing sewn into the Stick-It's interior. Those press-stud loops allow you to attach it to the bottom of any pack with MOLLE on its base.
I've put it on my Platatac Light Field Pack in place of its "Office" Admin Pack, or in fact as well as it. It also fits the Propper UC Pack, and the old standby the classic Platatac Bullock Echo, though the Echo already has a beaver-tail attachment built in.
The Stick-It has a couple of other interesting features. It is constructed to have expanding baffles in its Center line, in case of very bulky loads, with plastic inserts to stiffen the sides and carry the weight more evenly. You can really fit quite a lot into this, and is is the smaller of the two sizes offered. It also had a set of drainage grommets in its base, for those times you've taken a dip or been caught in a monsoon.
Another very forward thinking feature is the sheer length of the webbing for the attachment straps. This both lets you place the buckles anywhere from right at the back of the pack, to all the way at the front for quick release options of your over-load without shucking the pack propper. They also come with hook-and-loop keeper loops, to bundle the excess webbing up tight and out of the way for snag free utility.
The small Stick-It is perfect for stowing bulky times, like an Ops-Core bump helmet, a bundled jacket like the Platatac Harry 1.2 Softshell or the like. It can easily cope with even larger items, as long as you're comfortable with the, sitting out over the top of its top lip. The construction is hefty, and I suspect the weakest point would be the clip on the buckle. I've never had any trouble carrying my every-day items, let me know if any of you try lugging a ammo-can with yours.
The Stick-It isn't usually available as a stand alone item, but can be found in the Mystery Ranch Gunfighter pack, or through Hornest.

Review: Platatac - Tactical Crate
Build from carbon fibre bonded with inconel this bad boy can withstand over 16kn of force, 2000 Degrees Celsius, 10 sticks of TNT and pretty much anything a triple figure digger can throw at it.
The recently declassified Assaulters Milk Crate is a team essential item. With multiple lashing points for the Tuff Tactical Quick Release
Tactical Tie Off Point (TTQRTTOP) and light weight modularity the Assaulters Milk Crate is a must for all DA's.
Supplied with Two pieces of core flute and 4 black zip ties.
Available in 3 colours. (Blackout 1000x, Tactical Tan, Killer Wolf Grey)
Weighs just 6 grams.
RRP $499.00
Available for preorder 1st April 2016"
I've noted on the forums there may well also be a Blue Force Gear force-on-force trainer in the works as well, but reports also suggest that Multicam just wont stick to the frame. It's too high-speed.
Presumably you can add other modular features, but that may well come with package inserts
I was fortunate enough to have a couple come my way as well, and can tell you though mine were pre-release (note the unreleased Blaze Orange range-officer option peeking out underneath) and a possible SF/ SASR aquatic version in Blackout there.
These are some serious pieces of kit, with numerous uses around the bunker, in the field, and for all kinds of bug-out or bug-in use. They're so tough you could even transport perishable items like milk in them!
I'm hanging out for a possible titanium version, but I'm always a sucker for over-engineering.

Review: PowerPractical - Luminoodle
As first seen on Breach Bang & Clear ...
It might sound like a silly name, but the Power Practical Luminoodle is a serious product. At its heart, it's pretty simple. Take a 5-foot length of flexible circuit, string it with 26 LED's, give it a dual sided USB power plug, and sheath it in a waterproof case. Unlike a hand held flashlight, or a dangling lantern, having a flexible string of LED's means you can put a band of light where you want it, just where you want it and keep it there. That's what the folks at Power Practical have done. More than that, they put a fair bit of thought into how you'd actually use the thing.
I have a couple of other innovative pieces of kit from Power Practical; their power generating thermoelectric cook pot, the Power Pot XL, and a USB power regulator, the Practical Meter.
It's quite a nifty piece ...

Review: Para TPS Pulley systems
I love paracord. I love titanium, I love pulleys, I love Kickstarter so when a titanium paracord pulley came up on Kickstarter, I knew I had to get on board. I've covered a titanium paracord pulley system before, in the Ti2 PB-9 Parabener systems which live on my daypack, just in case. However, they are pretty chunky, being loaded with other features, and might be overkill when all you need is some lifting and shifting.
That's where there the TPS system comes in. A bare bones pulley system, it's a Universal Pulley System made from grade 5 titanium and ready to be used for making work easier and putting no matter what you're doing. Designed for paracord, or any other 4mm line of your choosing.
The TPS pulley systems are available in four formats, the TPS-2, TPS-3, TPS-4 and TPS-5. the number value corresponds to the number of "sheaves" which are the wheels inside the pulleys, designed and produced by Andrew of Root Designs R&D .
Root Designs spent a lot of time determining the design and materials they wanted to use in these pulleys. The side plates and pins are made of Grade 5 titanium (Ti-6Al-4V) because of its strength and corrosion resistance. The sheaves are made of a homopolymer acetal (which is a very strong plastic that is used for bearings because of its low friction coefficient, perfect as sheaves). The clip-in retaining rings are made of stainless (304SS made by Smalley).
Some serious design and research went into the development of these. Based on using paracord with a minimum breaking strength between 250-340 kg (650-750lbs) for Type III to IV paracords, a FOS of 3 puts the maximum breaking strength (MBS) of the pulleys around 2250lbs. These values were tested on a computer using failure-and-finite-element-analysis software. Bearing in mind that most civilian paracord is type II to III, with minimum breaking strengths of 180-250kg, (550-650lbs). Doing these studies are part of why Root Designs needed support from crowdfunding.
Having gone through rounds of testing and prototyping, they have pulley systems now rated for a Working Load Limit (WLL) of 68kg (150lbs) and a Tested Breaking Strength of over 900kg (2,000lbs). What does that mean? it means the TPS is recommended for loads of around 68kg, and is known to catastrophically fail at 900kg. Given type III paracord will take at least 250kg, my money is on the TPS working long after the paracord snaps, if you're looking at points of failure.
What's the big deal with pulley's in the first place? Mechanical advantage! Anything you need to move or lift, these pulleys can offer up to a 5:1 mechanical advantage with paired TPS-5's. By setting them up in sequence, and threading paracord through the sheaves correctly, the power of simple machines can reduce the effort needed by up to 1/5th of the force needed by a single loop alone. A single pair of pulleys halves the effort, three, a third and so on.
I backed for and received a twin set of TPS-5's and also got a TPS-2 as well. They can be used in a variety of combinations, or singly depending on your situation and need. One thing to remember that with all pulley systems, your ability to lift is only as good as your weakest component. Any attachment accessories (I've used two steel S-hooks from Ikea, so useful) as well as Type 3 paracord. However you also need to take into account the features of the load, and it's ability to haul itself, as well as whatever you are mounting your load too.
The other aspect to be aware of is the length of cord used. For every sheave used, the length of "fall" between the sheaves increases. This needs to be taken into account when reeving (lacing) the pulleys.
Pulley systems mean that someone with little hands and arms, like Tactical baby, can lift this 2.5L kettle full of water, and hold it, in her non-dominant hand, and nonchalantly pose for photos before bedtime.
Here's a tidbit of information from the Royal Canadian Sea Cadets Seamanship manual,
Parts of the Tackle:
a. Standing Block: The block that is anchored and is not moving. This block changes the direction of the running part.
b. Moving Block: The moving block is attached to the moving end of the rope (the end the cargo is on).
c. Fall: The fall is the rope that is rove through the block.
d. Standing Part: The standing part does not move. It needs to be secured to either the standing block or some other fixed position.
e. Hauling Part: The hauling part is the part that is pulled.
But acting as mechanical advantage gaining simple machines aren't all the TPS can be used for, you can combine these little workhorses to get other tasks done too. If you need to send some gear across a ravine, creek or river, or between abandoned buildings in a desolate wasteland, each pulley was designed so it could be used as a zip line shuttle. Setting up a static line and fitting one of the TPS's on it, with either one, two or three sheaves to spread the load over the line means you have a very stable and secure system for shuttling loads back and forth.
You could even use the spare sheaves to run pilot lines to haul back and forth, as well as for suspending your load. In other applications, you could even make a dog run, or other off-ground tethering system for pets or small people whilst out and about.
I even found that by setting the TPS-5 up in a cross-woven pattern, I could make a friction belaying zip-line, in the style of the mechanical decent RACK devices offered by Petzl
Being made from titanium, acetal polymer and stainless steel, they work great in harsh environments such as the ocean, or gritty, hot environments. They could just as easily be used on a fishing boat as in the bush. The limits to their application is really up to your imagination, and material strengths you have to work around.
One of the really nice design features is their small profiles. By using clipping retaining rings, the side profile of the pulleys stay small. The TPS-2 is5/8" x 1-1/2" x 9/16". The TPS-5 is 2-1/2" x 1-1/2" x 9/16".
Basically pocket sized, no matter how you put it. The pins do not stick out from the side plate as much as a nut or the head of a bolt would, which means they are far less likely to snag or catch, as well as reducing weight The TPS-5 weighs 45g (1.6oz) and the TPS-2 a mere 18g (0.6oz). Each pulley can be user-serviced if needed using common tools, and spare parts are available from Root Designs on their website. They also offer a snap-bolt which can be fitted in place of the machined pin, around the existing sheave, to offer a built-in attachment point in the place of any of the existing pins. This is an awesome addition to have designed in, and I'm kicking myself that I didn't put in for some with my pledge. However, there's nothing magic in the bolts, and it is just a matter of finding a bolt which fits, and somewhere to shackle your pulley!
This is the kind of gadget that you probably wouldn't think to pack in your bug-out-bag on first pass, but to kit out a minimalistic problem solving swag, you could do a lot worse than including a set of TPS's to give you an advantage over your environment!
That's where there the TPS system comes in. A bare bones pulley system, it's a Universal Pulley System made from grade 5 titanium and ready to be used for making work easier and putting no matter what you're doing. Designed for paracord, or any other 4mm line of your choosing.

The other aspect to be aware of is the length of cord used. For every sheave used, the length of "fall" between the sheaves increases. This needs to be taken into account when reeving (lacing) the pulleys.
Pulley systems mean that someone with little hands and arms, like Tactical baby, can lift this 2.5L kettle full of water, and hold it, in her non-dominant hand, and nonchalantly pose for photos before bedtime.
Here's a tidbit of information from the Royal Canadian Sea Cadets Seamanship manual,
Parts of the Tackle:
a. Standing Block: The block that is anchored and is not moving. This block changes the direction of the running part.
b. Moving Block: The moving block is attached to the moving end of the rope (the end the cargo is on).
c. Fall: The fall is the rope that is rove through the block.
d. Standing Part: The standing part does not move. It needs to be secured to either the standing block or some other fixed position.
e. Hauling Part: The hauling part is the part that is pulled.
But acting as mechanical advantage gaining simple machines aren't all the TPS can be used for, you can combine these little workhorses to get other tasks done too. If you need to send some gear across a ravine, creek or river, or between abandoned buildings in a desolate wasteland, each pulley was designed so it could be used as a zip line shuttle. Setting up a static line and fitting one of the TPS's on it, with either one, two or three sheaves to spread the load over the line means you have a very stable and secure system for shuttling loads back and forth.
You could even use the spare sheaves to run pilot lines to haul back and forth, as well as for suspending your load. In other applications, you could even make a dog run, or other off-ground tethering system for pets or small people whilst out and about.
I even found that by setting the TPS-5 up in a cross-woven pattern, I could make a friction belaying zip-line, in the style of the mechanical decent RACK devices offered by Petzl
Being made from titanium, acetal polymer and stainless steel, they work great in harsh environments such as the ocean, or gritty, hot environments. They could just as easily be used on a fishing boat as in the bush. The limits to their application is really up to your imagination, and material strengths you have to work around.
One of the really nice design features is their small profiles. By using clipping retaining rings, the side profile of the pulleys stay small. The TPS-2 is5/8" x 1-1/2" x 9/16". The TPS-5 is 2-1/2" x 1-1/2" x 9/16".
Basically pocket sized, no matter how you put it. The pins do not stick out from the side plate as much as a nut or the head of a bolt would, which means they are far less likely to snag or catch, as well as reducing weight The TPS-5 weighs 45g (1.6oz) and the TPS-2 a mere 18g (0.6oz). Each pulley can be user-serviced if needed using common tools, and spare parts are available from Root Designs on their website. They also offer a snap-bolt which can be fitted in place of the machined pin, around the existing sheave, to offer a built-in attachment point in the place of any of the existing pins. This is an awesome addition to have designed in, and I'm kicking myself that I didn't put in for some with my pledge. However, there's nothing magic in the bolts, and it is just a matter of finding a bolt which fits, and somewhere to shackle your pulley!
This is the kind of gadget that you probably wouldn't think to pack in your bug-out-bag on first pass, but to kit out a minimalistic problem solving swag, you could do a lot worse than including a set of TPS's to give you an advantage over your environment!
