Hi all,
First post and at the risk of telling grandma how to suck eggs (there's probably a thread on here for that!) I thought I would add my tuppence worth (and some pictures if I can work out how) to the evenk/falconer debate. I'm not sure if these knots are evenk knots or otherwise, however after much practising in an upturned chair I can now reliably tie two similar but slightly different quick release knots that I would use with a basha. One slips, the other does not.
Basically, once I have wound a loop round my left hand, pointed to the sky and passed my left hand (with the loop) under the main rope then I can make a non-slip quick release knot by taking a loop from the main rope through the loop in my left hand, then passing a loop from the loose end through the loop from the main rope. NB it is possible to end up with a slipping knot if there is too much tension in the main rope. The main rope needs to be allowed to form kinks as the loose end loops are tightened.
To make a slipping version I point to the sky, pass my left hand (with the loop) under the main rope, then pass another loop from the loose end through the loop in my left hand, then repeat to keep the knot from unravelling. The repeat may be described as stopping the knot from slipping, but I think what is meant is that the knot doesn't unravel. It will still slide along the main rope, unlike the first knot.
Hard to show without pictures but does this sound right? It works for me anyway!
