Review: Pocket Slingshot

 I took  a chance with Ali Express and bought myself a cool little gizmo that I'd seen online.  I got a pocket slingshot. These are really jut production version of a childhood toy that I remember fondly. In Victoria where I live, the humble Y shaped slingshot is a restricted / quasi-legal item, for whatever reason.

The concept is very simple, a plastic tube forms the frame to which an elastic pocket is attached. The pocket becomes the motive force to propel its projectiles. The package also included an archery brush attachment which is threaded and fits onto the plastic ring outer face, when the cover is off.

The elastic pocket is shaped to included folds and pleats to add to both its elastic potential but also add stress relief. In the old homemade pipe and taped on rubber washing-up glove fingers
 versions, the interface between pipe and glove always seemed to be the place where it would tear.

The plastic ring has a 5cm inside and 6cm outside diameter, and with either the threaded cap or the brush-bristled archery lid is only 3.5 cm deep. Its a very compact little unit. When the cap is on, the air can be expelled and the elastic pocket compacts down into the ring. Thusly sealed, there is even space for the ammunition of choice in the contained pocket.  I also bought a 100 unit lot of 6mm steel BB's and raided my daughters toy box for glass marbles. The third ammunition type are arrows.


When coupled with the archery lid, the soft round rubber notchings of the included arrrows protect the elastic pocket from tears that might come from traditionally nocked  arrows. The included arrows are only half-length more likely  to be crossbow bolts than traditional bow-archery shafts.




Now, it's hard for me to measure the functional power of the slingshot, as I don't have a chronometer handy, of an means to measure impact force. So all I can tell you about the force of the slingshot is anecdotal at this stage.  I did accidentally put a BB through the steel mesh of my front security door, hard enough to have it ping off the concrete wall on the other side of the street. (Always know what  you're shooting stand what's behind it!). I've managed to punch through a number of single and double thickness cardboard boxes.  I think I ill try soda cans and plastic bottles next. Glass marbles weigh more than individual BB's but also pack more mass. As with any caliber discussion: big and heavy hits harder but small and fast hits deeper. Further testing required.

It shoots pretty straight, and I've contentedly lobbed marbles the length of my house's long hallway into my target box. With no sights, aim is a matter of lining up the  pocket and the hang-held ring and eye-balling it. Using a couple of archery tricks like being aware of the archers paradox and practicing!

So, last night I set up a little range in the backyard. with a tactical crate as my target cage and partial BB trap. I put in a can of out-of-date Pepsi-Max and took a shot from a few feet away.  I wasn't wanting to do a test for realism, I just wanted to get a feel for its penetrative performance. At 2-3 feet away, and at a 2/3 draw, my BB hit in the bottom1/5 of the can, and in a riot of sugar-free foam, the can ruptured. After it finished draining I inspected the can and noticed that there was an exit hole too. I'd  call that a good trial run, though more testing may be required, I have a bunch of that old nasty Pepsi-Max siting around ...

So, the pocket slingshot is a fun little toy, and I suspect if you had a rodent or pigeon pest issue it might be a useful tool, and certainly fun for plinking cans with.  I don't think it would be much use hunting with, for anything bigger than maybe a squiril or rat ,and even then  I suspect you'd have to get a head shot. better to trap I suspect.

Review: Tensile style Skytent

I love tents and I love hammocks, and I've expressed a desire for one of the Tentsile aerial tents for a long time, but they are quite expensive. Not wanting to miss out forever, I kept an eye out and checked out AliExpress, where real things go to be replicated. For Giftmas I bought myself the one-person equivalent. I always feel a bit bad buying knock-offs but at the very least, its getting the very innovative concept out there.

So, given my ongoing stroke recovery and my work situation, we haven't ben able to go away camping, so I hadn't been able to tryout my aerial tent. Australia Day came around and we were invited to BBQ in a park, sounded like the perfect opportunity to try it out. I took some extra webbing strapping, in case we had trouble finding tree's to sling it on, but as it turned out the picnic table we picked was close to three gum trees. I unrolled the skytent from its stuff-sack bag and took stock.

The contents included the triangular base, made from webbing reinforced ripstop with a low (70D) Cordura number and (high quality silicon coating to give it a waterproof index of 2000-3000 mm) the base, which is about 4m a side, had built in reinforced eyelets for the two sets of shock-cord threaded anodised aluminium alloy poles and a light, waterproofed (to 1500-2000 mm)fly sheet to connect to.

It also came with three sets of 6m (19') loop-ended webbing, and shackles to for it to the base. At one end a ratcheting system for increasing the tension was supplied.

The base triangle comes with a breathable B3 bug-screen net with twin zippers. Built into the "roof" are two sleeves to feed the poles through to keep the roof in place and add stability when setting it up and to drape the fly over.

Once set up, which took a bit of doing (pro-tip; set the tent part up on the ground in the middle of your space, then string your straps. I rigged my straps with a truckers hitch. Getting partial tension on the tent to set it at a good height was just matter of sliding the webbing up to the right height, one tree at a time and tightening the truckers hitches once they were even. PRO-TIP 2: get the three corners as evenly high as possible. this will stop you sliding "downhill" on the slick ripstop nylon.

Once set up, the remaining slack can be eaten up with the ratchet, but this takes some doing. I'm glad we weren't setting it up in the rain. Once fully tensioned which it really needs to be, we put the fly on, which  had nylon hook hardware and shock-cords. The 240D fly has a single up-and-down zipper which coupled with the wide door in the flyscreen, makes a nicely framed entry/exit and window when pegged back. with its attached toggles.

The interior is spacious, the 4m sided equilateral triangle provide  almost 7m². of floorspace, with 1.2m (the almost 4') of loft, with its quite steep sides, there is  a lot of real-estate.

The wide webbing reinforcements throughout the base distribute weight nicely. I'm 192cm (6'4") and weigh 90kg (200lbs).  Laying right down the middle, legs splayed to the bottom corners, I was very comfortably supported.

This skytent is rated to carry 400kg (880lbs) and the heavy-duty ratchets buckles have a staggering 2.5 ton minimum breaking strength. Even so, the makers recommend only stringing it at a maximum 1.2m / 4' from the ground. As a good rule of thumb, you shouldn't set a hammock up from higher than you would want to fall from. Or climb into.

The supporting poles that give the skytent its vertical structure are seated in these washer equipped eyelets, and with the shaped ends of the poles, they seat securely and remain in place even with the rambunctious efforts of Tactical Baby. The seams are all also all double stitched. The whole tent is well finished.  I had had worries about the quality, given it was a knock-off, but it's been well made and put together.

All packed down, the tent weighs3.0kg or so, including the included webbing and the ratchet. and packs down into a stuff sack measuring 50cm x 20cm x 20cm. It's not too bulky nor heavy and would make an excellent addition to a backpack for a camping trip.

Internally as I've said it is spacious, but good set-up is key. if any one point of the triangle is higher or lower than the others the effect is a slow and steady slide to the lowest point.

I took it camping off to a full-emersion live action roleplaying weekend, "After The Fall" .

So I found myself three trees and set myself up. As with most tents, second time was much quicker and easier, and i'd had my lessons learned from my first attempt so it was pretty quick.  I even slung a second hammock along side, for lounging in when I was in my full tyre-armour kit. TO somewhat disguise the bright green of my tent and its fly sheet  I draped the whole thing in some scrim. One thing I didn't want was anyone tripping and falling onto me as I slept, so I put it a little higher than previously.

So high in fact I needed to step up onto one of my tactical milk-crates that I pack my camping gear into. I also stowed my kit under the hammock, off to one side from the Skytent, in case I did have a fall.

Inside at one of the three apexes was a pocket system which worked quite nicely with a jumper stuffed in it as a pillow. I used the zipper as an attachment point for my night-light as there weren't any internal loop hangers.


All in all I am both impressed by and happy with my SkyTent, and would heartily recommend you al lgo check out the original design at TENTSILE - Stingray

After an afternoons romping by Tactical Baby, and perhaps more roughhousing than was necessary, one of the poles has been warped and now adds an uneven curve to the dome, but no real issue there.  Certainly no fault in manufacture. I've managed to straighten it out a little but eventually  I might either replace it or run it through a pipe bender in reverse.

The Skytent handled nicely when occupied by two. even if one was little and bouncy and the other big and lumpy. Alas, I haven't tried it with two adults, but they are rated for it.

I put  a yoga mat in it when I camped, just as insulation, it was plenty comfortable to lay in in warm weather but any breeze below will chill you right down. Setting up an under-quilt like those made by the Go-Outfitters would work  a treat, but you'd need a triangular one.   

One thing I found was that the fly lifted and flapped about a bit, so I lashed it down underneath with some handy paracord.


All in all and excellent product and not just a gimmicky concept. all the benefits of a hammock and tent combined.


Pro-tip #3: set your doorway at chest height if you-re expecting friends to pop by. Nicer conversations for everyone when you can be eye-to-eye.

Review: knock off Gravity Hook

One of my friends lent me this piece to compare. I have covered the Fishbones Gravity Hook a number of times, and have been involved with beta testing, so my appreciation and bias is pretty well known.

It appears that the Kickstarted design that Eldrick Garcia and his team developed, over many iterations, and put into production has been copied and is now for sale and being plugged online. Now, I am all for free market, and it's inevitable that great ideas will be copied, I wanted to try at least to compare and contrast the two designs.

Here are the two hooks side by side, with the Fishbones version on the left, and the Molibao version on the right. You can see they are essentially identical, remarkably so. The "arms" of the hooks are essentially carbon-copy of each other. The arcs, bolt-holes, the middle-notch hole and even the curves of the hooks are identical.

The mounting hardware is different, but bolts and self-locking nuts are ubiquitous, as are the shackle loop at the bottom. No big issues with that, obviously.




The batarang cross-hook pieces indicate pretty well the differences between the two pieces however.


The Fishbone cross-hook is obviously thicker, which is true for the entire construction which is made out of 1/8" thick 304 stainless steel and all of the Gravity Hooks and weighs 360g all told.

You can also see the finish of the Fishbone hook is much neater, with the Molibao finish having a notch still present inside the cross-hook. Thicker steel means stronger steel in my books, assuming it was the same grade, which I have no way of knowing.



The differences between the thicknesses of the steel used between the two Gravity Hooks have been taken into account in the Molibao version, which was good to see.

The notch-holes were differently spaced, and adjusted to still ensure a good fit, so the hook actually works identically to the original.

Essentially, if you didn't know that it wasn't from the original manufactures and had one to had to compare with, you wouldn't know it wasn't an original.


One thing I wanted to cover, then, was the price point. I went back and checked the Fishbone website and the steel Gravity Hook is $39.99, the titanium version is $79.99

On the Nifty Thrifty Store site, where I -think- you can get the real deal (maybe, given the use of the official promo-shots) they are $65.37.

The Molibao versions are on AliExpress and other cheep-gear sites, but really, you get what you pay for. I know you're not supposed to be putting your life on the line (literally) with the Gravity Hooks, but, why not spend a little more, for a better quality, original product, and give back to the people who are doing the innovation in the first place.

Review: maybe 5.11 Tarani x14 karambit

We have friends who heard that I have a thing for knives, and fixing broken things, and they send a mashed karambit they were very proud of my way. It looked like it had been stood on, popped the main blade fixing screw, and some of the torsion spring and locking mechanisms had bent and warped. The belt clip had two missing screws, but the blade was in good shape, if a little blunt. I got out my TORX screwdrivers and set to work.

Once I found a spare main fixing screw I had in my parts-bucket, and bending and hammering the frame lock spring back into shape I was pretty satisfied that I'd rejuvenated the blade back into a functional state. The thing was, even fully screwed together, it seemed ... wobbly. I held it in my hand and looked at the 5.11 logo and Tarani branding and thought to myself "is this something that Tom Davin would have released?" I had some serious doubts.

I did a web-search on the listed data "5.11 Tarani X14 karambit" and all I came up with were Russian language YouTube reviews, and an Ali Express listing for a 5.11 Tarani x14 karambit.

I asked Omega for the 5.11 CUB Tarani Karambit that I got fer her a couple of years ago and held them side by side, the difference was immediately obvious. Even if the "x14" was an entry level, budget version of the "CUB", it just seemed too different, with a torsion spring rather than a linear liner lock. The molding of the scales was also a little bit off, not sharp enough or well finished enough to be a match to the 5.11 logo.  The scales and the frame were also not fully flush.

That might have been because of the damage it had sustained, but it seemed more likely, due to poor construction in the first place.

At full length it makes a 16 cm (6.3") arc, with the blade making up 7 cm (2.7"). At it's widest, the blade is 2.8 mm thick, and made out of 440 steel, half serrated for extra bitey cutting needs, and is apparently hardened to a 55 HRC rating. The surface is oxidation coated, for rust prevention, and marked with a very convincing 5.11 logo on one side, and the Tarani logo on the other. Weighing in at 120 g (4.25oz, it's quite light and lithe in the hand, the ring-loop fitted me well, although the gaps within the frame meant that if I gripped tightly, they could have dug in.

Its a nice enough knife if you're not looking for reliability, or quality and want to look badassed with your karambit. I will happily address my thoughts if 5.11 get back ti me, but overall, my impression was that this was a poorly put together piece.

Review: Card Sharp -credit card folding safety knife

My fellow blogger Ninja Space Monkey blogged about  getting his monkey-paws on one of these awhile back and I was lucky enough to get one as an early Giftmas present from my partner's boyfriend, who share several interests with me (obviously). He didn't have ANY of the issues in getting it that Mr Space Monkey did, as he acquired it from the improbable http://www.alibaba.com/ a site of dubious renown.

This is the Card Sharp, a credit card sized folding safety knife. 

Unfolded it is a little ungainly, the plastic body is flexible, not only along the folding seams, but also the main parts. It is a polypropylene type plastic, not polyethylene rather than the polyvinyl chloride (PVC) plastic of regular credit cards. The blade is recessed, which adds to the thickness of the unit overall, but also protects the edge, and the user, when it is stored. It locks into "safe" storage with a rotating disk which covers the tip.

A Series of lugs, and lug-holes can be seen on the opposing edges. These lock together when the blade is flipped out, to form the handle and keep the unit fixed in position.

When it is extended, the long thin blade is held quite snugly, and firmly bu the folds of plastic. Small crenelations at the back of the blade give a gripping place, and the folded corner that extends forwards of the blade acts as a subtle guard against fingers slipping forwards onto the surprisingly keen blade. The blade, being very thin, is actually akin to a razor or scalpel, with a very fine point, and whilst feeling very fragile, birdlike even, made quick work of this orange.

This is the kind of "keep in your wallet, purse or binder" blade that comes in handy when you have a box that needs opening, oranges sliced, threads and cloth cut and splinters extracted.

Not very Apocalypse resistant, perhaps, but certainly useful, and worth keeping on hand for those every-day occasions where having a little blade comes in very handy and you can be the hero of the moment, in your own small way.
