How strong is a nail knot (tied with a knot tieing tool)? It seems
significantly stronger than a fishermans knot. In fact, many times if I
try to break off the fly instead of breaking at the knot it breaks in
the middle of the leader!!

If pulled up right, it is stronger than the line

Check my site for other applications of the "nail" knot
