Sharpeners for Modern Hard Steels

We're pleased to be carrying these sharpening tools from the respected Swedish knife maker, Fallkniven. Their sharpening stones feature durable diamond and ceramic abrasives specifically designed for working with the hard steels found in today's top end knives.

Durable and Double Sided

The DC521 stone offers a generous 8-1/4" (210mm) x 2-1/4" (55mm) size, making it suitable for almost any knife. This bench stone is double sided, with diamond and ceramic surfaces that will sharpen well and maintain their flatness even when working with the premium steels found in many of today's top shelf knives. Both abrasive surfaces are to be used dry, with no oil or water. Upkeep of this stone is straight forward, with both the diamond and the ceramic sides requiring only an occasional cleaning with soap and water to keep them free of waste material and working optimally.

Diamond Side

The gold colored side of this stone is covered with 25 micron (about 600 grit) monocrystalline diamonds, then coated in titanium alumina nitride to make a fast cutting, durable sharpening surface. This diamond side is used to quickly restore the shape of your knife's edge.

Dark Ceramic Side

The dark gray side of the stone is a ceramic material composed of synthetic sapphires. Finer than the diamond surface, the ceramic side is used to refine the edge after shaping. Ceramic stones don't have abrasive particles in the traditional sense, so it isn't really practical to apply a grit number to them, but the feel of using the dark ceramic side is similar to using a hard Arkansas stone. It leaves a refined edge with a hint of tooth-iness. Unlike an Arkansas stone, however, the ceramic of this sharpener will cut super hard steels quickly and efficiently.

Thanks John, I am so glad to be working with people who know their products and how to use them. You have a very informative and well laid out website and I learned a lot. It was a rainy Sunday and I watched every video and read through each article. The information you provided was very helpful in teaching technique and helping me decide what to buy. Also your products are so well thought out, that no matter what stone you prefer (oil, water or diamond), there is a nice package available for a beginner. All of the products you put together each had their own advantages and believe me, each one spent some time in the shopping cart until I made my final decision.
