Photo: Here, Bill has rotated the toe into the wood, not pushed it. He talked a little bit about the different shapes and grinds, but impressed me by using nothing but a single tool – the traditional straight-edged, angled grind. First, of course, he showed how to get it quite sharp. Then he showed us how to hold it, with index finger pointing down one edge, so that the tool is like an extension of the hand, and the approach angle becomes instinctive.
