Compact manual sharpener

Two stage electric sharpener

A knife sharpener includes guide structure for accommodating thick blades of a knife. The guide structure includes a fixed guide surface having a convex portion to match a concave shape of the blade and a spring guide surface preferably has a convex portion to press against a hollow ground portion of the blade.

Sharpener for thick knives

A manual sharpener includes at least one pre-sharpening stage having interdigitating comb-like abrasive sharpening structure. The sharpener also includes a finishing stage having a pair of abrasive surfaced truncated conical disks as its sharpening structure. The disks are mounted on a rotatable shaft with the small ends of the disks in contact with each other.

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.

Combination sharpener having two sharpening components

A combination sharpener assembly which is particularly useful for fishermen, includes an electrically powered knife sharpener. A manually operated scissors sharpener is mounted in the recess of the housing for the knife sharpener. A hook sharpener is detachably mounted in a compartment in the housing of the knife sharpener. The motor for the knife sharpener is mounted in a sealed inner housing and can be selectively operated under either direct current or alternating current.

Manually operated sharpener

Combination sharpener assembly

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.
