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.
