Abstract
A new and improved blade sharpening angle guide for aligning and holding a knife blade or the like at a proper angle to a sharpening stone for manual sharpening of the cutting edge, the blade sharpening angle guide comprising: an elongated curved block having a longitudinal slot therethrough wherein a knife blade or the like may be releasedly held with the blade cutting edge extending a distance outside the slot whereby controlling the angle of the blade to a sharpening stone when the blade and block combination are drawn across the sharpening stone.
Claims3
A blade sharpening angle guide for aligning and holding a knife blade at a proper angle to a sharpening stone for manual sharpening of the cutting edge, the blade sharpening angle guide comprising:
- an elongated block formed of rigid smooth abrasion-resistant material having a planar top and an arcuate bottom whereby a semicircular cross-section if formed, the block also having a first end formed square, the block additionally having a second end formed curved whereby a point is formed, the block further having a longitudinal slot formed radially to the arcuate bottom whereby a knife blade may be received, the longitudinal slot also being formed orthogonally to the planar surface of the top, the block having two shoulders defined by the arcuate portions on both sides of the longitudinal slot whereby a sharpening stone bearing surface is formed, the elongated block moreover having two identical spaced apart lateral holes therethrough, the holes being orthogonal to the planar surface of the top, the holes extending from the planar surface of the block to the inside of the longitudinal slot;
- blade retaining clip means comprising a pair of identical channel-shaped spring members fixedly longitudinally disposed within the longitudinal slot, the spring members having a spine and two identical inwardly biased denticulated arms wherein a knife blade may be frictionally removedly retained, the spring members also having a mounting hole formed through the spine, the mounting hole having the same diameter as the diameters of the two lateral holes through the block;
- and
- mounting means between the block and the spring means.
