Product details

What this product is used for

Manual knife sharpening and edge maintenance, using the coarse face for stock removal and the fine face for finishing.

Red-black two-colour stone for coarse and fine sharpening

This red-black two-colour double-sided sharpening stone combines two sharpening stages in one stone: use the coarse face to remove material and establish the edge, then use the fine face to refine and finish it.

The stone is made with pure grade-1 alumina abrasive. Final sharpening results depend on the blade material, pressure, lubrication, grit pairing and operator technique, so confirm the selected specification with the intended knife or blade before bulk production.

Custom packaging and logo printing are available for OEM orders. Confirm the stone dimensions, coarse and fine grit combination, artwork and carton quantity before quotation.
