As the hands have gotten older, I have had to look for new ways to tie knots for joining two lines as well as tying on terminal tackle. I found a tool that seems to work very well tying the nail knot. I have been using the nail knot for terminal tackle and a nail knot to nail knot for joining the leader to the main line. I started using it a few weeks ago when I took a fishing trip for small mouth. The largest fish caught was around 31/2 lbs. So far, it has worked very well, with no break offs, but since I haven't seen it mentioned in bass fishing forums, I am wondering if I should be using it. Any inputs would be greatly appreciated both on the use of the nail knot or any other tools/aids to help these old hands tie reliable knots. Thanks
