Re: Best Stopper Knots for Team Supplied Knots

Oh man the Rock climber in me is cringing about some of the stuff I just read in this thread but there is some very good stuff in here.

A few points:

1, I saw spectra and Dyneema/ Vectra mentioned ( all just different names for uhmw-pe) Tying knots in these are very difficult and not recommended in the least as they dont hold knots. In climbing situations if you use these materials they are sewn together or if they do have knots you MUST have very long tails as they can capsize. ( There are other issues with these materials that I would love to talk about if your interested)

2, As for knot strength, the breaking strength of a knot is a function of the strength of the rope and the number and angle of the bend entering the knot, if you tie a knot and test to failure the cord almost always breaks at the knot. To this end the Figure 8 is the strongest knot you can use as it preserves the most amount of strength in the rope. If that is your concern this is your knot.

3. A very simple stopper knot widely used is the Barrel knot. Used widely to finish off rappel ropes to save climbers from rappelling off the ends of their ropes. Its very simple easy to tie and untie and expands the diameter of your knot. This knot will be limited by the size cord you choose to use.

4. When tying different ropes together very few methods beat a double fishermen in terms of strength but this works best with cord of a circular cross section. If using webbing you will want to use a water knot.
