Abstract
A device for use in the manual sharpening of arrow broadheads, razor blades and the like includes a unique symmetrical clamp and axle assembly having interchangeable, matched pairs of special purpose jaw members for gripping blades of differing configurations. When coupled to the frame, the clamp and axle assembly is freely rotatable, and this free rotation automatically aligns the length of the edge of the blade with the surface of a sharpening medium. Additionally these rotational and self-aligning capability enables the user to service both sides of the blade's edge with a single blade clamping operation, by manually rotating the clamp 180 degrees between passes along the surface of the sharpening medium.
Claims15
A self-aligning blade angle guide, comprising:
- (a) a clamp for securing a blade to be sharpened;
- (b) a frame operatively associated with said clamp so as to enable free rotational movement of said clamp relative to said frame;
- (c) a means for selecting a sharpening angle;
- and
- (d) a means for coupling said clamp to said frame in a manner which provides for free rotational capability of said clamp relative to said frame,
- whereby the weight of said self-aligning blade angle guide, combined with any added pressure applied by the user, causes said clamp to rotate on its axis when said self-aligning blade angle guide is placed in an operational position on the surface of a sharpening medium, thereby aligning the edge of a blade secured in said clamp with the surface of the sharpening medium, said rotational capability further enables the user to service both sides of a blade's edge with a single blade clamping operation by manually rotating said clamp 180 degrees between passes along the surface of the sharpening medium.

A self-aligning blade angle guide, comprising:
- (a) an axle having a first end and a second end;
- (b) a clamp for securing a blade to be sharpened, said clamp configured to operatively couple to said first end of said axle,
- (c) a frame configured to operatively couple to said second end of said axle,
- (d) a support structure for positioning the self-aligning blade angle guide on the surface of a sharpening medium for selecting a sharpening angle,
- whereby said axle, said clamp, said frame, and said support structure are coupled in combination in a manner which provides for free rotational capability of said clamp, enabling said clamp to freely rotate as the self-aligning blade angle guide is placed on the surface of a sharpening medium, thereby aligning the edge of a blade secured in said clamp with the surface of the sharpening medium, and further enabling the user to service both sides of a blade's edge with a single blade clamping operation by manually rotating said clamp 180 degrees between passes along the surface of the sharpening medium.
A self-aligning blade angle guide, comprising:
- (a) an axle having a first end and a second end;
- (b) a clamp attached to said first end of said axle;
- and
- (c) a frame operatively attached to said second end of said axle in a manner that allows free rotational movement of said clamp relative to said frame.
