Master Grade knife sharpeners were designed by an engineer and practitioner in the knife industry.
The benefit of his experience is transferred by technology and modern manufacturing to the
final user in the form of these high quality sharpeners.

Master Grade offers a unique feature in the commercial model, a flexible sharpening wheel that is
unlike the conventional stone wheeled units which tend to overheat and grind away blades. Users
will be delighted with this innovative sharpener which produces a razor sharp edge in just
seconds, clean edge just like new.
