This is the 1st time i have done a knot on my BS at 30*, don`t like it, next one is going to be at 45*. It is a modified slim, copper hardware, cherry wood. Other pic is a crimson flake acrylic cigar.
In don't think you are going to like 45° much better. Try 60° or 67.5°. You might like the 30° angle it you did a six ring knot rather than a four ring knot??
