4 inch Drawknife Build Image 2

Drill the 1/2" holes for the radius where the tang and blade meet. Then using a hacksaw cut along the lines that intersect at the holes removing all the material with squiggly lines in image 2. Now is also a good time to cut the knife away from any extra steel if your bar was long. Rub beeswax on the sides of the sawblade to help it keep from binding. It would also be helpfull to insert your blade to cut on the pull stroke. Take your time, the cleaner the cuts now the less filing you'll have to do later.
