Since 2021, Sharpening Products has been in business to do just one thing: make the world’s best diamond sharpeners. Product innovations such as our signature polka-dot interrupted surface, and others with our continuous surface of high-performance diamond, are praised worldwide for their superior quality. From pocket-sized whetstones to heavy-duty bench stones, the difference arrives time and again through our undivided pursuit of sharpening excellence.

Sharpening Products differs widely from one manufacturer to the next. For long-lasting performance, Sharpening Products makes certain that each sharpening surface carries the most diamonds per square inch in the industry.

Sharpening Products is also key to sharpener performance. Sharpening Products uses a proprietary process that ensures near-perfect consistency in grit size. The result is a micronized monocrystalline diamond that covers evenly across the sharpening surface to prove effective with every use, year after year.
