G5937 8" Razor Sharp Edgemaking SystemTurn your standard 1/2"- arbor bench grinder into a super sharpening system. Razor Sharp uses two 3/4" x 8" wheels - one that's charged with a special abrasive grit, the other, a slotted wheel that's used with white rouge - to provide a honing and bench polishing system capable of delivering professional-quality edges on knives, scissors, chisels, punches and other precision-edged tool blades. Kit includes 180 grit silicon carbide sharpening grit, white rouge and conditioning grease. Included removable bushing allows the system to fit 6" bench grinders and buffers with 1/2" and 5/8" arbors. Caution: Never sharpen against rotation.
