Here are a few things you should know about ceramic sharpening-rods sets. First, there are some truly lousy ones on the market. The two good ones that I know of are the Lansky Kitchen Combo and the A.G. Russell Ceramic Sharpener. The Lansky comes with three sets of rods ranging from coarse through fine and A.G.’s is fine only. Fine is all I ever use, and I don’t believe you can get a shaving edge without it.
Ceramic rods will never wear out, but if you drop them they are guaranteed to shatter. So don’t drop them. Also, I was not kidding about cutting your arm in the video. A knifemaker friend of mine cut himself so badly pulling that stunt that he had to go to the hospital.
