Device and method for processing a blade edge

摘要

A blade processing (e.g., sharpening) device includes two sets of overlapping edge processing rings Inner diameter surfaces of the edge processing rings define a notch suitable for effectively processing a blade with a convex cutting edge profile. Certain types of edge processing rings are movable relative to one another to adjust an edge processing angle of the notch. Certain types of blade processing devices also can also process blades with concave cutting edge profiles. The rings may be contained at least partially within a protective housing. A blade can be processed by inserting a blade through a blade insertion opening in the housing and into the notch while a handle of the blade remains outside the housing. By grasping the handle, the blade can be manually reciprocated within the notch during edge processing.

主权项

1. A device for processing an edge of a blade, the device comprising:
first and second edge processing rings having inner diameter surfaces suitable for processing the edge of the blade, the first edge processing ring being rotatable about a first axis and the second edge processing ring being rotatable about a second axis, the first and second axes being spaced-apart from one another, the first and second edge processing rings overlapping each other such that the inner diameter surfaces of the first and second edge processing rings form an inner blade processing notch, the inner blade processing notch being configured to receive the blade such that the edge of the blade engages and is processed by the inner diameter surfaces of the first and second edge processing rings, and wherein the first and second edge processing rings have outer diameter surfaces suitable for processing the edge of the blade, and wherein the outer diameter surfaces define an outer blade processing notch for processing the blade.
