Benefits of technology

The invention aims to provide affordable and reliable elements and arrangements using minimal equipment to achieve maximum efficiency. This will lead to improved performance and functionality in the intended application.

Problems solved by technology

Knives will become dulled with use and therefore periodically require sharpening.
However, a single grindstone can result in uneven grinding along the length of the knife blade edge.
Also, a grindstone may be cumbersome to carry and use if large, and may be easily lost if small.

Embodiment Construction

[0016]Referring first to FIG. 1, according to at least one aspect of the invention, a knife blade sharpener 100 includes a first sharpening member 102 having a first grinding edge 104 and a second sharpening member 106 having a second grinding edge 108. Referring also to FIG. 2, which generically and diagrammatically illustrates overall configuration of each of the first and second sharpening members 102, 106, the first and second sharpening members 102, 106 each have a generally circular circumferential surface 105A or 105B with a wedge shaped notch 112. In FIG. 2, the wedge shaped notch 112 is indicated by an arrow 110 indicating magnitude of an angle subtended by the sides 114, 116 of the notch 112. The notch 112 may subtend an angle of about ninety degrees of the generally circular circumferential surface 105 which generically represents the generally circular circumferential surfaces 105A and 105B. The notches of the first and second sharpening members 102, 106 represented by t...

Abstract

A knife blade sharpener including two generally circular sharpening members pivotally mounted about a pivot axis and having opposed grinding edges. The grinding edges are located along one side of a notch formed in each of the generally circular sharpening members and can be brought to face one another, adjustably subtending an obtuse angle therebetween. The pivot axis may be established by a screw and a knurled nut enabling the user to tighten the two generally circular sharpening members together at a selected subtended angle for sharpening. A knife blade may be drawn through a wedge shaped gap between the two mutually facing grinding edges, and thereby sharpened. The knife blade sharpener has resilient gripping pads and a holster which facilitates gripping as well as for stowage.

Description

FIELD OF THE INVENTION[0001]The present invention relates to sharpening tools, and more particularly, to a hand held knife sharpener.BACKGROUND OF THE INVENTION[0002]Knives will become dulled with use and therefore periodically require sharpening. It is possible to maintain a grindstone for this purpose. However, a single grindstone can result in uneven grinding along the length of the knife blade edge. Also, a grindstone may be cumbersome to carry and use if large, and may be easily lost if small.SUMMARY OF THE INVENTION[0003]The present invention addresses the above stated need by providing a compact knife blade sharpener having opposed grinding edges. The grinding edges are each formed on a generally circular sharpening member both mounted about a pivot axis for mutual pivot or rotation about the pivot axis. The generally circular sharpening members are pivotally adjusted such that a wedge shaped gap separating the opposed grinding edges corresponds to a cross sectional profile o...
