|
| It's simple and fast to tie (with a little practice for muscle

| kqr wrote:
| Do you know about the prusik knot, and the corresponding

|
| Works on the same principle as the taut-line hitch. You can
| hang your weight in the knot on a vertical rope
| indefinitely. If you can then find a way to unload the
| knot, you can slide it up the rope and then put your weight
| on it again, slightly higher up than before.
|
| So how do you unload the knot? By loading another of the
| same knots! So you alternate between loading and sliding
| the two knots, making your way up the rope with
| comparatively little effort and comparatively high
| security.
|
| It's quite amazing!

| KnottingKnots on Youtube is incredible at that:

|
| I think the knots I use the most, both in everyday life as well

| Figure of Eight knot (bend too but less often) - Sheet Bend
| - Prusik knot - Square knot - Taut line hitch

|
| For a single reference book, it covers so much quite well,
