Just finished watching "Building the Daniel Boone Rifle" from American Pioneer Video, featuring Mike Miller. Through the video it looked as if his chisel blades had two different angles on them. A long shallow angle for most of the blade, then a shorter, less shallow angle for the actual cutting edge. Am I correct, or is it an effect of lighting in the video? Mostly I leave the bevel on my chisels to the same degree they came, but I have changed a couple. What degree of bevel(s) do you other builders use on your chisels? Many Thanks.
