From Swedish Knife Maker Fallkniven We're pleased to be carrying 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, Double Sided, Folding Sharpener The sharpening surface of the FS4 is 3-1/8" (80mm) x 1-1/4" (30mm). Open, it measures 7-1/2" (190mm) long and closed it is 3-7/8" (99mm). It is spring loaded, opening at the touch of a button, and features a lock to secure it in either the open or closed position. This folding pocket sharpener 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 working optimally and free of waste material. Diamond Side The gold colored side of this sharpener 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. Ultra Fine Ceramic The white ceramic side is for finishing an edge to razor sharpness. This very hard and smooth ceramic material will leave a fine, close to mirror polish for a refined cutting edge. The surface it leaves on the metal is comparable to a Hard Black Arkansas, but this White Ceramic will work more quickly than an Arkansas, even on very hard steels. Made in Sweden
