A sharpening tool having a handle having a variable speed switch and a support grip, a removable universal tool adapter rotatably coupled to the handle, a locking feature for locking a position of the removable universal tool adapter, and a motor for driving a tool coupled to the removable universal tool adapter.

Knife and tool sharpener

A knife sharpener comprises a grinding surface for grinding a blade of the knife when the blade is moved relative to the grinding surface and an observation device including a sensor element and a display element. The sensor element is configured to observe the blade and to collect data regarding the blade when the blade is moved relative to the sensor element. The display element is configured to communicate a condition of the blade to an operator of the observation device. The condition of the blade is based on the data collected by the sensor element when the blade is moved relative to the sensor element.

Assembly for sharpening and observing wear on a blade

Sharpener

An electric sharpener for sharpening ceramic blades includes at least one stage. The stage is a finishing station having a sharpening member in the form of a disc which comprises a rigid support having a flexible abrasive matrix which both sharpens and polishes the facet of the ceramic blade. The sharpener may include a pre-sharpening stage for metal blades and a further pre-sharpening stage for ceramic blades. The sharpener also includes a removable guide.

Electric sharpener for ceramic and metal blades

Electric knife sharpener

An electrically powered knife sharpener for ceramic (or other brittle, crystalline or amorphous media which could be used for blades) knives includes at least one pre-sharpening stage with a sharpening member(s) and includes a final stage with a sharpening member(s). There are one or more motor driven shafts on which the abrasive surfaced sharpening members, such as disks, are mounted. Guide structure is provided to guide the knife for aligning and positioning the knife facet precisely at a defined location on the abrasive surface of each rotating sharpening member. The pre-sharpening stage sharpening member(s) moves in a first direction. The final stage sharpening member(s) moves in a second direction which differs from the first direction.
