So, update. I decided I didn't like the Andrea hitch (the hitch I named after my own mother turned out to be kind of shite). I can see it maybe failing if it were to not be dressed and set correctly, which requires more work than for the average hitch. It looks pretty freaking cool, but I give that one a fail. Fortunately, I was able to come up with a new hitch out of the ashes of this previous hitch. I'm running out of ways to introduce new hitches, so here it is...
...the DUALITY hitch, which is a complementary hitch to the Trinity Hitch and only because this one has two sections of wraps (the Trinity obviously has three) and because they were both inspired by the Schwabisch...or at least that's what I've been telling myself!
Attached at the bottom are front and back photos of the Duality hitch. One nifty fact about this hitch is that even though it is most definitely a directional hitch, it will grab readily when pulled in the opposite direction. I can imagine this being useful for something like alpine climbing where the routes are never just up or down, it's a mixture of ups and downs with one predominant direction ranging in extremes from sheer rock face to practically flat. So in a situation where a climber is predominantly ascending but with frequent downclimbs along the way, they might want something to catch them if they were to fall with direction of pull opposite the dominant pull direction. To at least prevent them from sliding, perhaps not a full body weight fall. If it were grab with a full body dropping on it, it would be after much sliding and rope melting, possibly even de-sheathing. All no bueno. Unless, of course, the top wraps actually grab nicely with the bottom wraps (with the force how I show in the video). My concern is that this design would cause the top wraps to collapse, thus leaving all of the weight on those two lower wraps.
Thankfully, you can reconfigure the wrap construction of this hitch just like any other hitch, allowing the climber to place as many wraps as they want in the catch side or the climb side! In theory, one could make the catch side the climb side and visa versa. A long hitch cord could even be used to create all kinds of helpful adjustments to this original form. Reversing climb side (where someone might try to tie this hitch 180 degrees rotated and apply climb forces in same direction shown in video) might be interesting to try out, but I don't recommend doing it unless its on the ground. It wasn't tied with that orientation in consideration and knowing the directionality of the hitches I want to make directly effects how I tie them.
Here's the obligatory "how to" video for your viewing pleasure (or displeasure)! I'm still learning to relax and be natural when a camera is rolling. I'm already awkward enough off camera. Yikes!
It's worth noting that I tied this hitch wtih a 32" cord. Normally, a hitch like this would be challenging and congested to tie using a hitch cord with sewn eyes. However, this is shown tied using a spliced cord. This is my first spliced eye to eye and it's amazing how much it opens the doors to more complex hitch making since it is possible to make use of the full length of the cord. I freaking love it! I certainly did not make it. Someone one this forum (if they want to take credit for this masterpiece, they can of course) who is both thoughtful and generous bestowed this piece of veritable hitch cord perfection upon me. It's a standard Sterling RIT sheath 9mm (my favorite diameter) with the usual Nylon core removed and replaced with braided (?) Dyneema. I've never been so inspired to learn how to splice as I am now. I'm not even blowing smoke, I'm genuinely this excited about a length of spliced fabric!
Oh crap,
@Burnham tried to warn me. My addiction is progressing and now I've gone from spending money on hitch cords to get my fix to prospectively making my own hitches...would that make me a manufacturer or a dealer? I guess I couldn't hit dealer status until other people are hooked on my hitch cords. Ha!
As always, if anyone tries this out, please share your experiences. I like this one a lot. You might even say it "tickles my fancy!" =-D
EDIT: I made an abundance up clarifications and typo corrections. Feel free to reread this if it made little to no sense when you first tried. I realize my writing is voluminous and most people probably won't read even half of it, but I'm still going to continue writing this way because it makes ME happy.
