Sometimes it is best not to mess with tradition.
I meant modern monofilament leader material, which is made of nylon. Before they invented nylon monofilament, leaders were made of silk and were much thicker, and knots made in them were weaker.
A Turle knot passes through the hook eye and is tied around the shank.

Thinner nylon tippets made it possible to tie the leader directly to the hook eye rather than the shank, with knots like the Improved Clinch.
