Refine Your Edge to Razor Sharp

Sharpening gets your knife sharp, but refinement is what makes it perform. The Whetstone Discs upgrade your sharpening system by smoothing and polishing your edge after the diamond disc. Using 3000 grit to refine and 6000 grit to finish, they unlock cleaner cuts, smoother glide, and longer-lasting sharpness—without the mess or learning curve of traditional whetstones.

BETTER THAN TRADITIONAL WHETSTONES

The Tumbler already makes sharpening simple, fast, and consistent. Whetstone Discs take it further—refining, polishing, and restoring your edge without the hassle, mess and skills needed to use traditional whetstones.
