How to Tie the Pop Lock Knot (An Innovative Bend) by TIAT

PDF Instruction Link: http://tinyurl.com/7poqj49

The "Pop Lock Knot": a means of connecting two cord ends quickly and securely for loading or general use, that also allows separation (while loaded or not) in a split second; even if the tyer's fingers have been compromised by cold weather, fatigue, or injury. Unlike historical bends, the Pop Lock Knot does not require dexterity to regain separate use of the connected cords. Video production and instructions by J.D. Lenzen of Tying It All Together (TIAT).

J.D.,

Could you name some examples of how this knot could be used/applied (for those of us who are not advanced knotters)?

Thanks!

[TyingItAllTogether]

- Here are four uses [there are many more]: * The knot could be used to quickly release an item that has been lowered from a greater height. * The knot could be used to quickly release tension on a bowed branch or limb, used as action in a snaring or snagging device. * The knot could be used to quickly release a taut line after use. * The knot could be used to connect to or more cords, and quickly allow the modification of total cord lengths at the PLK "Pop Points".

Have you put any significant weight/force on this knot? With how easily it pops loose, I would be concerned that it would slide loose under a good load.

I don't think this would work too well as a release on a snare. From the video, it looks like it takes some force to pop it. Most snares need a hair trigger to work.

[TyingItAllTogether]

- Yes (to date) about 180 pounds of force have been applied to the knot (i.e. my full body weight) and no slipping occurred. As for snares there are more than one type. My comment regarded "lie-in-wait snares" (typically used for larger game animals). This said, there is no need for perceived concerns or beliefs regarding the PLK, simply tie the knot and check it for yourself. Most theoretical possibilities are easily tested with two strips of cord and 10 minutes (at the most).

Interesting thought process you have there Mr. Lenzen. What looked to be another variation of a Solomon bar turned into a useful thing. This leaves me wondering if this bend could be used in a life safety application. (rope rescue, etc.) I anchored one end of the paracord, applied the bend and pulled. The bend only tightened and did not give way before I got tired. I will apply this in our life safety training ropes at the FD. I will forward my results if you wish and give you due credit.

- I'd love to hear how that goes... The primary reason I'm presenting this knot so thoroughly is so others can know it completely, and try it out for themselves. Best to you!

It's quite limiting that it can't be easily tied when any standing end is already in use though.

I tied this a few times to try it out, but found that when it was tight enough to hold, it was too tight to easily release. I tried it in 6mm kernmantle utility cord, and in braided nylon clothesline, and neither worked very well.

Is there some situation where you'd prefer this knot over, say, a slipped sheet bend?

Just a follow up: Haven't tested the PLK in life safety applications and sadly, we won't be. Orders from a higher rank than me. However, it is a practical extension of our utility knots and has already found use in a woodland fire. It was slow to apply because of the new-ness(?) but worked well without failing. Note: the fire mention was contained, only then did we apply skill sets that needed work, the PLK was an add on. Thanks!

Hi JD

Nice knot and interesting concept, but isn't a simple slip version of a knot easier and faster to tie?

[SquirrelFromGradLife]

or you could tie a Zeppelin bend with slip ends even faster that comes apart more easil.. never seen one do it outside myself. You should try it.

[peacefuljeffrey]

I would like to see, then, a video that shows the knot tied using only two free ends. Any plans to do that? Thanks.
