I've used a lot of unorthodox tools since I've been making bows. When I first started all I had was an ax, drawknife and an old hunting knife I used as a scraper. Eventually I acquired all of the usual tools used by most bowyers.
About 15 years ago I had a man named Bill Reynolds in one of the bow classes. He is a farmer by trade. If you are familiar with farmers you know how inventive some of them can be. About 5 years ago I had Bill come and give me a hand with one of the classes I was doing. When he got to my place he said I want to show you my latest new tool, a chainsaw blade. As he was going after it I was thinking, what in the world is he up to. He then brought in a chainsaw blade, and said he used it for a scraper. He had both a 12" and an 18" blade.
After trying it out, I instantly became a fan of the chainsaw blade. It is great for peeling off the extra wood before you get close to the final tillering. I'm sure we are not the first to use them on bows.
I have been both a carpenter and a toolmaker most of my life and can appreciate a good tool when I find one.
