I had a beval edged paring chisel that was made up from an old file, it was surface ground on all edges then flatted out on oilstones to get the sharp edge, I could only pare wood with it as it would shatter if struck with a mallet but it never lost its edge while in my ownership. Sadly it went west with all my tools on the boat coming back from Canada 1971. Now I have had one remade in the old style.
