Nail knots aren't tested often, but when they are there is a lot on the line. It is worth getting it right, but best to avoid spending all afternoon cursing and trying to find a substitute for a solid knot tool. The Ergo Knot Tool makes nail knots easy and comes with clear instructions on how they are to be tied.
The Loon Ergo Knot Tool works very well as an aid to tying those pesky knots, especially for one with bad
eyesight. My old eyes don't work so well these days and this tool takes the pain out of tying knots.
