Having twice outlived the Chef's Choice 2-year warranty, I have had two Chef's Choice knife sharpeners fail in exactly the same manner. Plus, I like to freshen a blade with a sharpening steel at every use and the patented Chef's Choice 3 stage sharpening method is not compatible with the steel.
The Tormek T-7 is awfully compelling. If I used chisels regularly, I would be buying one of these today, but I think it is overkill for my knife, scissor and occasional axe, hatchet and chisel sharpening requirements. Do watch the video, but I think Tormek do themselves a disservice by trumpeting the 150 page hardback manual and huge array of jig options. It seems more like a lifestyle than an intuitive tool.
