A major breakthrough in sharpening technology, this award-winning design provides all your sharpening options in one compact appliance. It professionally sharpens, steels or strops all brands and types of kitchen knives--straight-edge, serrated, Asian-style-as well as sports and pocket knives. Three-stage electric sharpener obtains a "better than factory" edge quickly and effortlessly. Stage 1: using 100% diamond abrasives, sharpens the edge. Stage 2: a super-hardened miniature steel develops a shaving-sharp edge with ultra-sharp microscopic teeth, providing a superior edge "bite." Stage 3: a revolutionary flexible stropping disk polishes the edge to hair-splitting sharpness. Using these stages in different combinations produces custom edges suited to particular cutting tasks. User-friendly angle guides guarantee foolproof sharpening. Assembled in USA.
