How does a glass scraper work?
A broken piece of glass can be used like a cabinet scraper. You can even get it to make very fine shavings. Can anybody explain how it cuts? Every other woodworking tool – chisel, plane, cabinet scraper — has a true cutting edge. The cutting edge digs into the wood when you push the tool along the wood. However, I don’t think a glass scraper has such a cutting edge. It has a very sharp edge, but it is aimed backwards as the scraper moves along the wood. How can this cut wood?
