Abstract
Both facets of a double faceted blade are simultaneously sharpened as the facets are moved across a first pair of planar abrasive coated surfaces crossing to form a vertex and positioned to establish a total included angle at the vertex nominally equal to the intended total included angle of the edge facet. A guide structure contacts and aligns the blade so that the centerline of the blade is positioned at or near the bisection of the included angle of the abrasive surfaces. The guide structure is one or more rotatable members.
