Knife Sharpener: How it Works
Carbide Sharpening Surfaces
Unique, ultra-hard, precision ground tungsten carbide sharpening surfaces, like those used in high-precision machine tools, quickly create a more perfect “v” shape and a superior cutting edge. With a simple change in hand position, these sharpeners also fine sharpen (hone) and polish a perfect beveled edge.
The carbide sharpeners are mounted on patented spring-action bars that adjust automatically to accommodate different blade angles. With the variable angle capability, our sharpeners work beautifully on serrated knives and single-bevel Japanese knives, as well as standard smooth knives.
Long Lasting and Durable
The sharpening mechanism is durable and can be expected to last at least 5 years with normal use. Replacement sharpening bars are available for the Professional and Classic countertop models.
