This hitch is similar to the Gnat Hitch, with the exception of the final tuck.

Say I wanted to tie something tight to a loop without slack, but have it be super easy to untie, what would you suggest?

Pretty knot i made in my walking pad safety string during work : r/mildlyinteresting

OP is u/lillykimy

Been working on a project for a knot web app and just looking for some feedback!

Each knot is a 3D animation you can pause, slow down and orbit. Flip to the other side or switch to ‘your view’ to see it as if you're the one tying.

Currently working on an offline mode as well as a few more bits to come!

Looking for feedback as I only have 18 knots animated right now. Which ones should I do next?

Thanks all :)

Hi knot bros!

I'm back with a followup after testing some of these hitches/knots. There were also some other questions that I can answer at the end.

For this surgical use case (gripping a tendon or ligament so that I can pull strongly in the direction of the tendon I tested a few knots. The variables that really matter for this application are strength, stiffness, and how easy the knot is to tie/dress. Something I hadn't mentioned about this use case is that I'm trying to tie the knot arthroscopically/endoscopically so I have to be essentially building a ship in a bottle. Specifically surgery to reattach rotator cuff tendons to the humerus or meniscus to the tibia. Sometimes I can use a knot pusher to push a knot into place but mostly I prefer to tie it outside of the joint and then slide it into the joint.

The knot that came out on top in my informal testing was the wittstein suture loop which was described for non-arthroscopic surgery by Wittstein in 2011. This hitch seems the best because it has been very easy to tie arthroscopically and was very consistent in its strength and stiffness. If you're interested in reading about it there's a decent article abstract from a biomechanical study here and theres a link to the free pdf on the page.

knots like the prusik, icicle hitch, MFT, MRH, swabisch, klemheist, autoblock are in the "A tier." when properly tied and dressed they have equivalent strength and stiffness. In fact, these knots are all so strong that they never pull out of the tissue or cut thru the tissue. Instead, they fail when the suture breaks. Since they have equivalent strength and stiffness choosing a winner came down to the ease of tying and in an arthroscopic demo they were significantly harder to tie than the wittstein suture loop.

clinch knot, FG, nail knot, constrictor, anchor were all very reliable to tie in the open but I have no faith in my ability to make them work intraoperatively. Maybe new tools in the future would make them feasible.

Thanks to all for the suggestions on knots to try and resources! It was fun learning some new knots, I feel like I added some tools to my toolbox.

Shoutouts and QA in no particular order:

u/elciteeve shoutout for mentioning directionality and angles, key principle for suturing and knot tying

u/SAI_Peregrinus shoutout for Ashley's book of knots, it was overdue to get a copy, loving the chapter on friction hitches

u/Sybian999 your idea for the fingertrap is a proprietary design called the Speedtrap! This is a pre-tied finger trap that works "ok" in an open setting. Unfortunately nothing like this is available for arthroscopy. Acrylate would be a really cool tool to have available but as far as I know it would only work in open sugery as my arthroscopic cases are underwater and the acrylate wouldn't polymerize properly. As much as I'd like to have a patent it's not likely that I'll be able to do that, I can't imagine that the PTO would let me patent a knot.

u/DeadFacesInMyPocket I neglected your question about removing sutures. Typically we don't go back to remove a suture from a "deep layer" as it would be an extra surgery and the material is inert so unless it's actively causing a problem we will just leave it alone. this is true in other disciplines as well, thoracic surgeons leave prolene sutures in the heart/aorta. They also use the same sort of suture material (UHMWPE) to close the ribcage and that gets left behind permanently as well.

u/Dayruhlll shoutout for going out of your way to demo the bury/splice, great demonstration :)

u/slides_galore I neglected your question about the knots we use. Most of the time we finalize our sliding knot or hitch by "backing it up" with a series of half-hitches. This is either done by tying square knots or by tying "reversing half-hitchs on alternative posts" aka RHAPs (see the SCOI knot I was discussing with u/poeepo in the OP). RHAPs or square knots are the gold standard for a knot stack that will resist loosening. In other situations if we can't/won't tie half-hitches we can secure the sutures with a knotless anchor eg an arthrex swivelock. I have in some situations used a cleat hitch which I've never seen described before, maybe I'll publish the technique ;)

u/pgm928 keep hating lol

It’s a little stupid, but I tied this into my phone case and I can’t figure out how to remove it. After I untied whatever I did it was just stuck like that even though I swear I it was the same when I managed to get it in and none of the parts were attached after. Don’t know if this is exactlyyy what the sub is for but if someone knows anything.

Does anyone knows if someone has ever achieved a mathew walker knot on wire?

Any info is helpful thankyou

I’m very basic in my knot knowledge. I prefer having a small but well practiced knot library in my head. That said I need a knot to cinch and stop a rope passed through a round dowel with hole drilled in it. The rope will pass through another dowel at the opposite end with a hole and a non sliding stopper knot, then I need to tension and hold the line on the opposite side of the other dowel, after the rope is passed through. My only thought is a slip knot with additional stopper knot? Anything more clean?

I tie a knot that weakens the rope by 60%. I tie another one that weakens it by 40%. In this case, when buying a rope, I should base my decision on the 60% reduction—because if it can withstand the knot that causes a 60% loss in strength, it will certainly withstand the one that causes a 40% loss. Is my reasoning correct? And what if the knots are very close to each other?

Any help would be appreciated…

edit: I got it. Y’all can stop sending advice now. Everybody here who helped was very much appreciated.

Saw this at a Renaissance Faire and thought it looked needlessly complicated but then I saw the exact same setup guying down a shade structure at a wedding and I figure I must be missing something.

For context, it’s used to tie my car shelter.

I need to reproduce those and I have no idea how. And the rope is really tight.

I have a pot with 3 screw eyes for hanging. What is the best method to stably hang this using a rope? Bonus if the rope stays in one piece, since it will get wet and moved enough that unraveling is a potential concern.

Thanks!

I just wanted to share today's discovery, no promo here, I just love ropes and knots!
It’s a little physics software called Algodoo!

Have fun!

It is on the end of a grand trunk portable hammock!

I was on a bike ride with somebody the other day and he had like 3 voile straps of different sizes in his bag and said, " I never go anywhere without my voile straps. I was just like, here is rope and a knife, learn how to tie knots and you'll never need those things. Seriously, there are like dozens of adjustable friction hitches and fixed loop knots that are more reliable than anything those straps can a accomplish and it's extremely lightweight, compact and you don't have a metal piece awkwardly sticking out. The lack of knowledge on knot tying has reached concerning levels. I just feel like it's mandatory knowledge if spending any significant time in the outdoors where the weight and space are limited.

(I’m a beginner at knot-tying, sorry🙏.)
I’m referring to knots where the load is held by just a single loop (the figure-eight follow-through or the bowline). Beyond a certain load, every rope will break—but does it happen at some part of the knot, or rather at the loop itself? Since the loop bears the load, is that where it will break? This is especially relevant for single-braid (which have no inner core) and thin ropes. Am I right? (Yeah, I’m aware that in critical situations—such as climbing—thicker ropes are used, and they are always kernmantle ropes, but my question is just curiosity)

I believe it’s an eight strand round braid or something like that. I plan to add a carabiner clip on the dog end and a handle of some kind on the other.

Any ideas?

What would you call this knot?

It is basically a double fisherman's tied over itself. The knot can slide up and down without being untied.

What use could this be handy for?

I made it up when someone showed me an adjustable sling that I still am not sure what the purpose for it is for.

It does not change the length. Only the position of the knot. Same with the adjustable sling I mentioned above.
