This is the title of an item posted by a Fine Woodworking contributor to the website's blog -Finding Center, woodturning tips tricks and techniques- on June 3, 2013. Recommending using files found at yard sale or flea markets as tool steel, the contributor writes "Transforming a file into a scraper takes only a couple of minutes. Grind away the teeth on one face, working an inch or so back from the edge." Is this foolproof? The contributor goes on to say that Beth Ireland gave him tools made out of allen wrenches. Isn't this a totally different tool steel?
