Yeah, that's just what it looks like. I don't think I said it was cylindrical anyway. For that reason you have to be careful because as you push this thing into the gullet you can screw up the shape. Then I rub the flat side of the knife with it, then draw the knife across a piece of wood to remove any wire edge. Most bread knives are crap, in my opinion. The ones we had at the country club were awful..blades too flexible. We have them all over the place at the earthy crunchy grocery, the ones with the white plastic handles, real grinding service units, but they work fine.
