Abstract
A glideway crowning plate for creating a crown on a cutting edge of a cutting blade with a sharpening jig including a glideway crowning plate having a concaved curved surface of a predetermined radius placed proximate spaced glides of a sharpening jig. The sharpening jig utilizes a flat sharpening plate or a flat sharpening stone and the sharpening jig is side-stroked on the flat sharpening plate or the flat sharpening stone and the glideway crowning plate imposes a curved path of the predetermined radius on the sharpening jig, the cutting blade, and the flat sharpening plate or the flat sharpening stone to create a crown in the cutting edge of a cutting blade.

A glideway crowning plate for creating a crown on a cutting edge of a cutting blade with a sharpening jig, the glideway crowning plate comprising:
- a glideway crowning plate having a concaved curved surface of a predetermined radius placed proximate spaced glides of a sharpening jig, and
- wherein the sharpening jig utilizes a flat sharpening plate or a flat sharpening stone and the sharpening jig with a cutting blade therein is side-stroked on the flat sharpening plate or flat sharpening stone and the glideway crowning plate imposes a curved path of the predetermined radius on the sharpening jig, cutting blade, and flat sharpening plate or flat sharpening stone to create a crown in the cutting edge of a cutting blade.
A method for creating a crown on the cutting edge of a cutting blade with glideway crowning plate and a sharpening jig, the method comprising:
- providing a glideway crowning plate including a concave surface of a predetermined radius;
- placing the glideway crowning plate proximate spaced glides of the sharpening jig;
- placing a flat sharpening plate or a flat sharpening stone proximate the front of the sharpening jig, and
- side-stroking the sharpening jig with a cutting blade secured thereto on the flat sharpening stone or the flat sharpening plate such that the glideway crowning plate imposes a curved path of a predetermined radius on the sharpening jig, the cutting blade, and flat sharpening plate or flat sharpening stone to create a crown in the cutting edge of cutting blade.
