Review on 🔪 Experience Enhanced Cutting Control with the Nicholson Triangular Double American Pattern by Kevin Bucher

This file was not enough to sharpen a 9 inch 14 tpi saw. It cuts great for the first few teeth but after a few inches I had to switch to a different plane than the same. By the time I got to the last tooth, this file had barely cut through on all three sides. It just slipped over the tooth. I do not recommend this file for sharpening saws.
