How do the three stages work?

The coarse carbide slot sets a new edge, the ceramic slot hones it, and the fixed diamond rod sharpens serrated and specialty blades. Use the carbide stage only when the edge is dull.

Does it work on serrated knives?

Yes. The diamond-coated rod is meant for serrated and specialty edges. Draw each serration along the rod rather than using the pull-through slots.

Is it better than a whetstone?

It is faster and far more portable, but a whetstone gives more angle control and removes less metal. Use this for quick touch-ups and a stone for full sharpening.

Will the carbide stage wear out my knives?

It removes metal quickly, so repeated use shortens blade life. Reserve it for edges that need resetting and hone with the ceramic or diamond stage in between.

One compact knife sharpener. No case or extra rods are included.

Is it covered by a warranty?

Milwaukee backs it with a limited lifetime warranty. Keep proof of purchase for a claim.

Our take on the Milwaukee Compact Knife Sharpener

The Milwaukee Compact Knife Sharpener is a small pull-through sharpener with three stages: coarse carbide for quick edge setting, ceramic for honing, and a fixed diamond-coated rod for serrated and specialty blades. It weighs under an ounce and has a large finger loop, so it clips to a pocket or bag and stays controlled while you pull. It suits tradespeople, campers and home cooks who want a fast touch-up in the field rather than a bench stone. Against two-stage pull-throughs it adds the diamond rod for serrated edges; against whetstone systems it trades edge quality and long-term control for speed and size. Owners rate it highly for convenience, though some find the carbide stage aggressive and the plastic body light.

Pros

Cons

Carbide stage removes a lot of metal fast, so use it sparingly
Plastic housing feels less sturdy than the abrasives
