Surgical sharpness in 3 simple steps.

No soaking stones, no complicated hand posture, and no ruined knives. Knivratix is engineered to bring professional sharpening results to every British kitchen counter.

Snap Blade to Magnetic Preset

Place the magnetic base on your worktop and attach your knife spine against your chosen angle setting with the blade facing up.

2

Roll the 400-Grit Diamond Disc

Gently roll the coarse diamond cylinder back and forth along the entire edge until an even, uniform burr forms along the blade.

3

Polish With the 1000-Grit Disc

Flip the roller to the fine 1000-grit side and glide back and forth to deburr and hone a silky, razor-sharp edge ready for cooking.

"Absolutely brilliant piece of kit for our kitchen in Surrey. I could never master whetstones and always feared ruining my Japanese chef knives. With Knivratix, two minutes of gentle rolling produced an edge sharp enough to cleanly shave paper!"

"Our kitchen carving knives were completely blunt before Sunday roasts here in the Cotswolds. Used the 400 grit first to restore the edge, then polished with the 1000 grit side. Slices through beef brisket like warm butter now. Truly well-made timber construction."

"We threw away our cheap carbide pull-through after seeing how Knivratix works. The magnetic angle block keeps everything rock steady without any wobble on the worktop. Restored my entire 6-piece knife block in twenty minutes."
