Product description
Diamond Hone® Model 220 Knife Sharpener combines advanced electric and manual sharpening techniques to create an exceptionally efficient blade for almost any knife. The cutting edge is finely shaped for extreme sharpness, but it retains its strong microscopic teeth which gives it a very effective "bite" for all your food preparation needs and especially for fibrous materials.
Model 220 is designed to sharpen at 20° angle any American, European and Asian style domestic use knives (two-sided, such as Santoku), pocket knives and certain hunting knives or those used in hiking. Do not attempt to sharpen scissors, ax blades or any blades that do not fit directly into the slots. NOT recommended for ceramic knives and Asian-style knives that have traditional one-edge blade.
Model 220 has two harpening stages, the first stage performed with the help of a motor, followed by the modeling stage, which is entirely manual and allows a precise sharpening, which will be done depending on the purpose of the knives. Each sharpening stage has a precise role and must be carried out properly, so that the knife blade be well sharpened, shaped and ground.
In Stage 1 (sharpening), sharpening is done with the help of an electric motor through two slots (left, right) which help create the facets with primary edges, formed at a nominal 20 degrees on each side of the edge, which leads to an overall 40-degree edge and to the occurence of metal burr.
Stage 2 (finishing) creates a second inclination at a slightly higher angle leaving a strong and burr-free blade edge, which will stay sharp for longer. Serrated blades can be sharpened only in Stage 2, so that not much material is removed from the surface of the teeth without needing that.
Always make sure that the knife blade has been thoroughly cleaned before starting the sharpening process.
The complete sharpening process for a 20-cm blade knife takes about 2 minutes, and for knives with shorter or longer blades, the duration of the sharpening process can be longer or shorter. Once the knives have been sharpened using Model 220, resharpening takes less than 30 seconds.
The sharpener will be maintained only by manual cleaning with a damp cloth.
