Diamond Rolling Knife Sharpener Set

Our rolling mechanism seized up immediately, but it doesn't really matter; this is a bad sharpener even on its best day. Even if the angle guide's magnet weren't so weak. Even if the rolling mechanism weren't so apparently fragile. Even if it weren't so bad at reaching the tip and heel of many (if not most) knives. Ultimately, its grinding disc is just too coarse and there's nothing you can do about it.
