Sharpening saws is a skill that has always eluded me. More often than not, I’d wind up with a saw out of joint with funny looking teeth that would either cut so slowly as to make a snail’s pace seem like Mach 5, or would jerk in the cut.
Each time I had to sharpen my saws, especially the finer toothed ones, I would dangle my chicken bone necklace around the saw handle and offer a small sacrifice of sawdust, praying that this time it would work.
It wasn’t for lack of information; I’d sought out as much information as I could, but nothing seemed to work to point where I actually understood what I was doing and how to replicate the results.
Yesterday I finally realized what I was doing. The saw file simultaneously shapes the front of the tooth while sharpening the back bevel of the adjacent saw tooth. By concentrating on the adjacent saw tooth’s flat after jointing, I was able to get a perfectly uniform tooth height with about 1 or 2 degrees of rake. There are about two inches towards the end of the saw that are a little bit wavy, but those areas will be rectified with future sharpenings.
