Abstract:

Method of and apparatus for indexing a workpiece to a tool at a predetermined angle of orientation, using a bubble level to establish a horizontal reference plane. The bubble level may be pivotally fixed to a housing of a jig which may incorporate a magnet for adhering the housing to a magnetically responsive workpiece. The bubble level may be secured at a particular pivotal orientation such that when the workpiece is held against the cutting or abrading surface of a tool, the workpiece may be manually maintained at the predetermined angle of orientation such that a ground surface disposed at a predetermined angle on the workpiece may be formed while holding the workpiece manually. The jig may incorporate an adjustable leg to assist in tightening the bubble level at the particular pivotal orientation.

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.
