Even a good knife will lose some of its sharpness with time. Sharpening a knife can be easy if you have the right tools and know how to use them. A sharpening stone, or whet stone, is the best method of sharpening fine edge knives because of the control it allows. Like sandpaper, sharpening stones come in a variety of roughness or grain; the coarser the finish the more abrasive. Whet stones can use water or oil as a lubricant; water stones are much more convenient. For regular sharpening with a stone, use the TWIN® Stone Pro (250 and 1000 grain). TWIN® Finishing Stone Pro is used for a professional, scalpel-like and mirror finished edge (3000 and 8000 grain). Both stones are ceramic, manufactured materials that require minimal water and last longer than natural stones. Sharpening with the TWIN® sharpening stones may need some practice but the results are well worth the effort. Watch our how-to video and learn to properly re-sharpen a knife.
