Posted By: Dan N.I made the terrible newbie mistake of attempting to use a beautiful Blue Steel Japanese chef's knife to separate lamb chops (cut through a bone) and was rewarded with a 1mm deep nick in the blade edge. I used this basic diamond plate to re-shape the knife edge and prepare it for the remaining work, done on a succession of Shapton Pro stones (1000, 2000, 5000, 8000). The knife turned out great and I've been using it ever since. So as a very coarse shaping tool, this plate does the job.
Unfortunately, when used as a flattening plate for the stones, I noticed that it just was "missing a spot" in the middle. Turns out, the diamond plate is concave by about 1/4mm at the midpoint, meaning that the stones become slightly convex after "flattening". Not going to use this again for flattening.
Just bought a DMT plate, which I expect will be flatter and of better quality.
