Naniwa Diamond Pro 1000 Sharpening Stone

The Naniwa Diamond Pro #1000 is a professional-grade diamond stone built for regular sharpening and blade upkeep on the hardest steels, picking up where a coarser stone leaves off. We recommend it for efficiently sharpening hard stainless steels like HAP40 and ZDP-189, which cause conventional whetstones to dish quickly; the Diamond Pro's resin-bonded diamond surface stays flat instead. It needs only a splash of water to use, with a small dressing stone included to keep the surface true over years of use.

• #1000 diamond grit handles regular sharpening and blade upkeep on the hardest steels, refining the edge after coarser grits like the #800
• Resin-bonded diamond layer on a metal base holds its edge and stays flat far longer than traditional whetstones
• Splash-and-go design—just add water, no soaking required
• Includes a small dressing stone to keep the diamond surface flat and performing at its best
• Made in Japan, part of Naniwa's professional-grade Diamond Pro series
