Using forceps to quickly tie a Kreh Loop Knot
Since the clinch knot is a direct line-to-fly connection, the line may impart some unnatural motion to the fly. If you prefer having the fly swing independently of the line, use a loop knot. The most natural loop knot to learn and fastest to tie using forceps is the Kreh Loop.
Forceps eliminate the poking, prodding, squinting and foul language usually involved in tying invisible tippet to a microscopic fly. After practicing a few times, adding tippet or swapping flies takes seconds instead of minutes. Given the apparent truth that to catch fish, the fly has to be on the water instead of in your hand, quicker knots equals streamside happiness.
