Guess I had better tell everybody about the easy way to tie the Eugene Bend\Pitzen\16/20 knot with hemostats.

Hold the fly in your left hand\eye pointing right.
Take the tag through the eye of the hook and back towards the standing line.
Then take the tag back towards the eye of the hook, forming an open loop.
Hold about 3/4 of an inch of the tag in your left thumb and index finger.
Then insert the closed hemostats into the open loop you have just formed. Twirl the hemostats five times around the standing line which will form a sort of clinch knot around the standing line with the open loop.
Then slightly open the hemostats and grab the tag and pull it through the clinch that you have formed. Keep pulling but do not fully seat that part of the knot. Just close it enough that it will not pass through the eye of the hook. You can then remove the hemostats, lubricate the knot and pull on the standing part of the line to seat the knot. You will feel the knot "turn over" as it seats which will mean that you have done it correctly.
I know it sounds complicated but it is really quite simple. You can even do it with gloves on and it is a much stronger knot than the clinch.
Tight lines and tall tails,
