The Tormek system isn't good for flattening the back of a chisel which you have to do periodically. Moreover, it puts a slight concavity on the bevel. Purists don't care for it, but it is easy. I've been sharpening with a Borg Water Cooled Rotating flat stone for years (I just set it in my utility sink and let the water drip on it from the faucet) followed up by a couple of Japanese stones for honing the edge. Works fine and is fast (and cheaper too-the Borg runs about $150.). Sharpening stones all the way through works just as well once you get the hang of it. Like anything, there is some skill involved-and a learning curve, albeit a short one if you pay attention. David Love davidlovepianos at comcast.net www.davidlovepianos.com
