So I finally got around to sharpening some blades yesterday—several chisels and a plane iron. Everything was going fine. I have a honing guide but I just felt like doing it freestyle. Also, I usually do the Scary Sharp method with adhesive sandpaper on a slab of granite. This time though, I got out an old, two-sided water stone that I haven’t used in years. I went through several chisels and the plane iron and got hair-shaving edges on all of them. But on the last chisel, I put the bevel down on the finest stone, pushed it forward and gouged the heck out of the stone. It removed a little furrow almost an inch long. There is plenty of room on the stone, but I hate that I damaged something that required more care. In the future, I’ll either use my honing guide or just avoid orienting the chisel that way. For my purposes, the stone will work fine, especially given how rarely I use it. But I’m wondering if anyone has a method for resurfacing a water stone.
