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: Fishbones - Carry-all hook

Here is an interesting piece of kit that came from the same minds as the Gravity Hook, and Fishbones, Piranhas gear ties. It's the kind of thing that I would probably make for myself if I had a metalwork workshop myself, where Brent & Eldrick Garcia of Out-Tek, LLC saw a need, and made something to fit the need.  This is the Carry-All.

Basically, Brent didn’t want to see his guitar constantly getting knocked over. So he made this thing. It’s basically a stainless steel hanger that can be fitted with either a length of nylon webbing or paracord.

Massively over-engineered, it is way stronger than it needs be, and that opens it up to my favourite kind of gear. Rugged, multifunctional and simple.

The body of the Carry-All is cut from a single piece of 3/16" stainless steel, the main hook opening is based around a 4cm (1.6") radius opening, much like a regular coat-hanger hook, and certainly wide enough to loop over all manner of pipes, racks, ledges and branches.

There is a finger grip section much like on a trench knife, with has a 2.5cm (1.0") radius opening, which is plenty of room for even a gloved finger, and there is enough room for two fingers, and along with the back side thumb-riser "guard" allows for a very secure grip which in turns allows for a quite comfortable hold-point for using the Carry-All as a carry-handle.

It isn't climbing rated, and Brent only mentions holding up to 45kg (100lbs) but I suspect you could carry more than would be comfortable before it breaks.


Designed to primarily take 1" webbing, the Carry-All has two sets of twin webbing slots, one narrower, one wider. These enable you to friction lick the webbing easily, as well as doubling the feed over to ensure a really secure lock. Looping both ends of the webbing through the eyes forms a webbing loop that can then be used for the Carry-All's primary purpose, to grab and hang awkward, unusually shaped and odd pieces of kit, be they the neck's of guitars, a pole to form hangers, or any other sort of webbing strapable item, which could do wit ha hook to attach it to a suspension point.

So hang your awkward stuff up to 100 pounds. I would like you to have one too.

With an overall length 12.5cm (5") and 7cm (2.8") wide, the 3/16" stainless steel is hefty and as sturdy as you could want, whilst still being essentially pocket-sized. The 18" 1" webbing supplied could be swapped out with any other 1" webbing, but as well as this, there are three paracod sized holes drilled into the base of the hook to facilitate stringing it with paracord instead.

It seems a odd piece of gear, it served a particular role, but also with a whole bunch of new options available for hanging, strapping and suspending, especially if traveling and you want to keep a bag of wet ground, for example. The balance points are well placed, and the stonewashed finish is easy on webbing and paracord alike.

I also envisage using these for picking up cast-iron pots from firepits, carrying twine-bundled loads of kindling, and stringing guy-lines for tarps.

Review: Fishbones - Gravity Hook (production)

Production on the left, prototype on the right

I covered the original release of the prototype Gravity Hook back in March, when the prototype was sent my way by the guys from FishBones. Not long ago the final production version of the Gravity Hook arrived, with some improvements.

The Gravity Hook is a combination grappling hook, and gravity claw. (Here's their promotional video...) By removing the middle cross-bar the more than serviceable grappling hook can be quickly converted into a claw-machine like grabbing claw. The clever design allows you to swap between these two features in just moments.

Production on the right, prototype on the left

The whole assembly weighs around 360g in its stainless steel configuration, a complete assembly includes 3 links, 3 "hammers", a cross hook, and hardware, in bolts and self-locking nuts.

One of the production improvements is the notches cut into the throat of the hammer, these allow the cross hook to seat much more securely that in the prototype, where it was held in place solely via the notch cut into top of the cross hooks. 

Production on the right, prototype on the left

The stainless Gravity Hook is made out of 1/8" thick 304 stainless steel and all of the Gravity Hooks hardware hardware is also stainless. When the hook is fully open, the 1.5" mouth will hold over 165lbs when biting into a 2x4.

When fitted, the cross hooks set in the jaws of the hammers, the Gravity Hook up as a quite effective grapple. The jaws are held in place and stopped from opening the by the twin o-rings which seat in a set of notches cut into the link pieces, and hold the jaws surprisingly tightly.

Production on the bottom, prototype on the top

 Given their design, any the pull on the tines of the hook only act to pull it further closed, the effect of the o-rings is really quite sufficient.

FishBones have suggested that an after market modification, drilling a hole in the middle of the hammer arms to fit a locking pin, for extra security, but so far, I haven't felt the need myself.

The bolts and locking nuts supplied with the production model are a much slimmer profile than the nuts and bolts I picked up at the hardware store, that was a big help.

The production version has nicely rounded notches cut into the links, where as the prototype version is rather a bit more rough making it rougher on and harder to remove the o-rings.

Production on the right, prototype on the left

One of the other backers of the Gravity hooks asked if they wanted to use it as a boat anchor for an inflatable lake boat, how they would dislodge it should it hook onto something on the bottom. Another backer suggested it could be set up with a failable style link like this  where if you pull hard enough the top link breaks and lets you pull the anchor from the bottom. A second way would be to use 2 ropes; one attached to the shackle, and the other looped through the claw to act as an emergency release in case the hook snags.


Here's me testing the grappling hook


Here's me testing the claw feature on a variety of dropped gear.

Two kinds of cross hook: plain and gear-tie batarang!

 You might ask "what makes it high performance?" well, this is probably a matter of its features:

• It can be used either as a 2 or 4 pronged grappling hook.
• In the claw mode it "bites" objects that might slip out of a grapnel.
• Compact enough to be stowed on a back pack strap, by clamping the jaws over the strap and feeding the tail end through a loop
• Can be dismantled into its base components for more compact storage. 
• It's available in stainless steel, titanium or even non metalic Derlin.

There are also two options for the cross hooks, with the classic solid hook, as well as a version with cut-aways, both lightening the cross hook, and also offering a place to use it as a gear tie, not unlike the FishBones and Piranha gear ties these guys came to the front with. 

Ss, you have a very cool tool in the Gravity Hook, but what are its limits? Well, the Gravity Hook was specifically designed for retrieving. It has not been tested or certified to bear human weight. The makers strongly state that you should never use it in a situation where it's failure or dislodging might cause bodily harm or property damage. In a pinch though, it can certainly take a fairly hefty load:

How do you get the Gravity Hook to release something whilst under tension?



Here's their testing underwater!


As well as being a really useful dropped-gear and treasure retrieving claw, and a sturdy and rugged grapple, the Gravity hook is also a really well made piece of engineering. I really appreciate its design and functionality. I've got a small CountyComm grapple, which is billed as a trip-wire clearer, but for bigger jobs, when you want to snag, yank and retrieve gear, or haul something you would do well with one of the FishBones Gravity hooks.

Better yet, the guys at FishBones have just launched a NEW project, the Gravity Hook XS, a pocket sized version, in just two-pronged format, on KickStarter. You should totally go check it out, and add some grabby, grapply goodness to your loadout.

Review: Fishbones - Gravity Hook

I've been lucky enough to snag a couple of prototypes for a Kickstarter project that has just a few days to go, and I really wanted to get the message out to you all, so you can take advantage of the situation, and back this awesome project. This comes from the same folks that brought us the Fishbones and Piranha gear ties.

This is a tool, called the Gravity Hook, which  can be used just as a 2 pronged hook, as a grappling hook with the addition of a cross-hook or, in its primary format, as a grabbing hook.

It is designed to "bite" objects that might slip out of a grapnel, much like The Claw, from a claw game.

A complete assembly is made up of includes 3 linking bars, 3 "hammer" arms, a cross hook, and nut-and-bolt hardware. A bow-shackle at the end gives you a cord-attachment option.

The whole assembly weighs around 360g in its stainless steel configuration, and a mere 60g in the high-performance Derlin plastic.

Notches cut into the linking bars as channels allow you to affix o-rings, which really help when tightening hardware. They are used to help keep the jaws tightened around the cross-hook whilst set up in the grappling hook configuration, and also during modification by keeping the parts lined up, to let you thread the bolts more easily. I've covered a small grappling hook before but this blows that right out of the water.


Bear in mind that the two version I have are prototypes, and by following along with the Kickstarter campaign there have been several improvements thus far. Notches in the jaws where the cross-hook sit should eliminate the slight wobble that the base of the cross-hook gets when in the grappling hook configuration. This was more noticeable in the Derlin prototype, but from the 3D renders I've seen this will be completely eliminated in the production model. The Derlin model also has a double set of o-ring channels, one high, one low.

I tried the low set as a place to store the o-ring I was using, but found that the added tension reduced the bite that the hook had, and combined with the low weight of the Derlin version, I found more success with the o-ring slipped off the hook entirely. The other difference in the two models are a couple of extra sets of holes in the Derlin version, presumably for threading extra bolts through to "lock" the grappling hook in place.

Two designs of cross-hook are seen as well, the solid version in stainless steel retains the weight and all the strength possible, but the cut-away version more closely matches the hammer-arms of the main body, as well as acting as a gear-tie, following n the footsteps of the Fishbone and Piranha.

Compact enough to be stowed on a back pack strap, I also found that the pair of Gravity hooks, along with their cross-hooks, and a length of paracord fit nicely in a Platatac FUP pouch. I carried both around in my cargo-pants for a few days, trying them out on various things to grab and hook, and  found that I needed to be careful which side the shackle bolt was sitting but the rest was easy to carry comfortably.

Here's a safety note: the Gravity Hook was specifically designed for retrieving kit and grabbing things. It has not been tested or certified to bare human weight. The guys who designed them have done some car-towing and some anecdotal destructive testing but stress to never use it in a situation where it's failure or dislodging might cause bodily harm or property damage. As with any climbing or salvage work, always use good judgment. You are responsible for your own actions and decisions. In an emergency, you might need to take extraordinary measures, but the risks are also extraordinary. Failure to follow these warnings could result in property damage, severe injury or death. Be prepared for anything, don;t become a casualty.

So, all that in mind, I really like the Gravity Hook. It's going to be a part of my EDC from now on (because I like to roll as heavy as I can get away with). Having this kind of gadget is exactly the kind of thing that I get to be a hero for carrying, at some stage, always. The Derlain version means I even have an airport safe version to take with me on any abrupt mountain-side landing trips I might be on.

Get in quick, back them on Kickstarter and remember: Always prepare to be a better version of yourself. Unless you can be Batman, then be Batman.

Review: Fishbones - Fishbone gear ties

Having covered the most excellent Piranha (which was their v2 product, but I got those first), I wanted to give the little sibling a trial before showing them to you, to get a better feel for their utility and differences.

These are the Fishbone gear ties (v1). You can see from the picture here that there are in fact three metals offered 1) 6061 T-6 Aluminum 2) 304 Stainless Steel and 3) Titanium. The aluminium and steel versions share the same exact geometry, where as the titanium is a little more "rounded".

The guys from Fisbones were good enough to send me a few of each to play with, but I've mostly focused on the steel ones. Why three options? well, in their own words:

Aluminum:

• Resists corrosion
• High strength to weight ratio
• Can be anodized in different colors
• Non-magnetic
• Nonsparking
• Light weight

Stainless steel:

• Resists corrosion
• Bright appearance
• Normally non-magnetic
• Great fatigue and impact resistance
• Durable

Titanium:

• High strength to weight ratio
• More than twice as strong as aluminum
• Almost half as light a steel
• Non-magnetic
• Excellent corrosion resistance

Measuring in at 14mm by50mm (½" x 2") and 3mm (1/8") thick, the Fishbones are smaller and thinner than their bigger siblings, weighing in at 3g  for aluminium and 9g for steel. When subjected to strain testing (by the makers), the aluminium slightly deforms at 36kg (80lbs) and has major bending at 72kg (160lbs) Note: projected total failure is only (135lbs). The stainless steel Fishbone only took a slight bend at 72kg (160lbs) in initial prototyping. Subsequesnt  That's a fairly impressive static load for a gear tie. Obviously, as with the Pirahna, these are not climbing rated, but for tying down gear, rigging tent flys or washing lines, that is heaps. 

As with the Piranha there are numerous ways to tie and apply the Fishbones. I especially like the detail given by Brent and Eldrick in their Kickstarter proposal in their examples of how to use them.

The geometry of the Fishbone lends itself to tie-downs, with a wrap and tuck type locking, using a Prusik-like friction bind on the paracord, and sharing the load between the ribs of the tool.

The eye-hole, and "gill-slot" give solid "head-forwards" ties, whilst the forwards facing pelvic-fin and ventral ribs before the tail fin give you three separate attachment points. On the dorsal side of the Fishbone, there are four shallow notches, and one deep one, all allowing purchase of your cord, and letting it bind tightly in a variety of configurations.

One of the things I really liked about these, are the clean straight lines, which enabled me to rig them to act as a zipper pull without having to worry about snagging, in such a way that I could also quickly detach them and use them to rig a line, or tie a bundle.

The stainless steel versions acted as a nice plumb-bob when rigged correctly, the nose pointing down, in a clean straight line.

I usually have a couple of lengths of 40cm paracord in my pocket, and idly fiddle with these at meetings and on the train, working out new combinations of ties and looking for new uses. Alas I had oped that the tail would fit into the A/C vents on my train, to enable me to latch myself in when there was no hand-hold but no.

I've found the Fishbones to be very handy little gadgets to have on hand, especially when, as often happens, I have had to bundle something up that I know I will need to unbundle shortly and quickly. Blankets, jackets and jumpers. Tactical Baby's favourite woobie and the like.

I think these will make a good addition to my cord and carriage kit, giving me quick-release tie options, and keep all my things snug and squared away without having to worry about knots binding up and keeping me from my fit when I need it. They make great gifts too!

Unlike the Piranha, the Fishbones didn't interlock neatly, so a 'head to head" clasp wouldn't work. No great loss though, there are plenty of other options.

The guys behind these even posted their original concept built to Instructables so you can have a go at making your own low-strength wire prototype version.

Review: Fishbones - Piranha

Yes, here I am again with another Kickstarter project. I'm actually reporting this one out-of-sequence, as through some kind of fulfillment time warp, this is the second of two projects that Brent and Eldrick Garcia put forwards. The first being their very cute "Fishbones" but I haven't had a chance to properly review those just yet.

These are the "v 2.0" product, the Piranha "Knotless gear tie"

As you might have noticed, I am rather enamored of paracord and so should you be! It's great stuff, but one of its great advantages can also be a disadvantage. It holds great knots! Sometimes trying to pick apart a tightly cinched knot can be very arduous, and Brent and Garcia came up with a very elegant solution with their Fishbone tools.

The Piranha is the result of a number of design stages, and really offers great utility as well as a great aesthetic.
Cut from 3/16th" thick 304 Stainless Steel the Piranha measures 60mm (2 1/4") from lip to tail, and 28mm (1 1/4") from crest to fin. There is also a titanium option, for the mass-conscious.

It fits nicely into  MOLLE channels, with the dorsal fin hooking neatly over, and being held in place with the tail-fin notch. I found that that tail-fin notch was a snug fit for Type 111paracord, which proved to be very useful in snagging and camming the cord into place.

Speaking of camming, it is worth noting the Fishbones teams own warning about these devices

"Note: Not for climbing or load bearing applications where failure would cause damage or injury."

So, with that in mind, lets have a look at some of the fun things that you can do with them.

The stonewashed edges of the steel are smooth and rounded,  having been sharp cut originally, but that significantly bites into the cord, so the current models are rounded to avoid this.

You might worry that the rounded edges would slip and not hold the loops, as seen above, in a top and bottom view of one of my preferred hitches, but they hold fast.

The two hook gaps are sized to interlock, giving you a solid connection of two ends of cord if you prefer.

Splicing two lines together is also a breeze with the Piranha, simply by winding one through the other, friction will hold  the lines together, even once tension had been released. Again, here are top and bottom views of this splice.

This was a really nice way to link two ends of cord together, without adding a knot that would likely bind and bite, making undoing troublesome.

One of the things I liked about the balance of the took, was that the "tail fin" notch allowed a loop to be fitted snugly, and dangled to make a fish hook. I successfully snagged and hauled my Bullock Echo from one of its D-rings through this method. For extra security,  I could have threaded a leader through the keychain opening, but that hole is too small for paracord, unless you are using the inner cord after gutting it.



 I also found that I could set three lines simply by using the dorsal notches which gave me a no-slide anchor from which I feel would give a very adequate hold for a tent guy rope, or any other three way roping you might need.

The versatility, small size and light weight (well, at just over 25g per unit in the 304 stainless steel) means that this is going to find its way into my EDC in no short time. If nothing else, they feel great in the hand or pocket, and gives me a fidget-focus when I need to keep my hands busy.

The hook gap also doubles as a bottle opener, adding some multi functionality that I really appreciate, as well as the other uses that the guys behind the Piranhas have already stated.

One of the awesome things that they offered is a quick summary of some modifications that you could apply to the Piranhas. I'm going to give a couple of these a try (and I'll get back to you with how they turn out ... )

 I also found that I could wrap the Piranha around an already strung line, given sufficient slack, to give a mid-line attachment option. So many options, such versatility. I'm also going to cover their original Fish Bones and the heavy-duty Snapper so stay tuned!
