The Marbles 6 in 1 Sharpener measures 4 by 4.75 inches with carbide coarse grind, 320 ceramic rods, 1000 ceramic honing, 320 scissors, single blade carbide and 1000 ceramic for bread knives.
A separate slot for bread knives is the detail worth noting. Serrations are sharpened on the flat side only, and running a bread knife through a standard V slot flattens the serration tips and ruins it. Most multi-slot sharpeners ignore that, which is how serrated knives get destroyed by well-meaning owners.
Six stages cover a full progression from carbide coarse grinding through 320 ceramic to 1000 ceramic honing, so a badly dull knife and a nearly sharp one both have the right starting point. A dedicated 320 scissors slot handles the outer bevel without touching the inner face, which is what scissors need and knives do not. Explore more sharpeners.
