Key features

01

RESTORE WORN STONES TO LIKE-NEW IN MINUTES Your whetstones dish out with use, and a cupped stone ruins your sharpening angle — and your edges. This dual-grit flattening stone re-levels any waterstone, oil stone, or ceramic stone fast: most users flatten a badly dished stone in about 5 minutes and rinse it off flat as new.

02

Dual Grit Does Coarse and Fine

ONE TOOL Use the 120-grit side for coarse water stones (900 grit and below) where you need aggressive cutting, and flip to the 320-grit side for fine stones (1000 grit and up) so you don't scratch a premium finish. No guessing, no second tool, no changing sandpaper.

03

FULL 8-INCH SURFACE FLATTENS ANY STONE At 7.99" x 2.79", the flattening area is large enough to true a full-size whetstone in one pass instead of working it in sections — faster, more even results with less effort than compact flatteners.

04

DIAMOND-GROOVE PATTERN CLEARS THE MESS AS YOU WORK The diamond-shaped groove pattern channels away slurry and waste while it cuts, so the abrasive keeps biting instead of clogging. Tip: work at the sink under a light water flow with a towel handy — the slurry builds fast, and rinsing as you go lets you see your progress and speeds up the job.

05

Premium Silicon Carbide

CUTS QUICKER, WEARS SLOWER Built from high-quality black silicon carbide chosen to remove material fast while holding its own surface longer than soft flatteners. Backed by Sharp Pebble responsive support — if anything arrives less than flat, we make it right.
