Our take on the Tumbler Pro Diamond Rolling Knife Sharpener Set

The Tumbler Pro is a manual rolling knife sharpener: you set the blade on a magnetic holder and roll a diamond-plate wheel back and forth along the edge. The fixed-angle design takes the guesswork out of honing and suits both home cooks and professionals. It comes with a storage case and needs only a wipe to clean. At $71.99 at eBay as of November 6, 2026, it is the best new price among the two stores listing it.

Cons
  • No angle adjustment, so the edge angle is fixed

Questions and answers

Is the Tumbler Pro worth it over a cheap pull-through sharpener?
Yes, if you want a consistent edge. Pull-through sharpeners remove a lot of metal fast; the diamond rolling plate hones more gradually and holds an angle. It costs more than a basic pull-through but less than most electric sharpeners.
Does it work on serrated or ceramic knives?
No. The diamond plate is meant for plain steel edges. Serrated blades and ceramic knives need different tools.
Do I need to adjust the angle?
There is no angle adjustment. The holder sets a fixed angle, which suits most Western kitchen knives but will not match every Asian-style blade.
What is in the set?
The rolling sharpener with its diamond plate, a magnetic knife holder and a storage case. No oil or water is needed; wipe the parts clean.
When is the best time to buy?
The best new price was $71.99 at eBay as of November 6, 2026, with two stores listing it. Watch for holiday kitchen sales, when knife tools are often discounted.
