Edge Pro Diamond Matrix Resin Bonded Sharpening Stone 80 Grit 1x6

Sale price$166.00 Regular price$171.00

The 80 grit Edge Pro Diamond Matrix stone is made for extreme metal removal. It is such a coarse sharpening stone that we do NOT recommend that you develop a burr with this stone. You should either stop just short of a burr, or remove metal at a slightly lower angle with the 80 grit than what your primary bevel will be sharpened at to preserve the cutting edge.

Unlike the other Matrix stones, it is recommended that you use the 60 grit silicon carbide for resurfacing this 80 grit sharpening stone.

  • Ideal for the modern "super steels"
  • Works great for sharpening ceramic knives 
  • While we do all we can to reduce voids in the stone we cannot guarantee all stones will be free of them. These voids will not interrupt the sharpening performance.
  • No soaking needed

Fast Sharpening on Blades

These resin bonded stones sharpen very quickly. With many of the modern steel alloys used in knives and tools, speed of sharpening can be an important factor when considering a resin bonded sharpening stone. These stones work well on very tough tool steels such as A2 or D2 and very hard stainless alloys popular in Japanese and western made cutlery.

Recommended for High Quality Finishes

Zanvak have been highly impressed with the quality of these bonded stones. Whether you're purchasing the very coarse 80 grit or all the way up to the extremely fine 4000 grit, we’ve found these stones to be very consistently graded. If you’ve considered purchasing a set of Resin Bonded Stones, we certainly recommend the Edge Pro Diamond Matrix Resin Bonded Sharpening Stones.

Splash and Go Resin Bonded Stones

If you want to get down to the real details of these stones, they are made with a resin bond. The resin bond gives these stones two real benefits. First, the resin bond allows for a higher level of abrasive particles compared with less expensive methods of stone bonding.

The higher abrasive levels contribute to the speed of sharpening. Second, these resin bonded stones don't require soaking in water prior to use, just a sprinkle on the top is all that is needed.
