[ What is claimed is:] [1.] A stop-bar for use in a knife sharpener to limit by direct contact the travel of an elongated knife blade edge with facets formed at a sharpening angle to a blade axis adjacent to each side of a cutting edge, said bar including a contact member having a strike face set at a predetermined angle to a vertical axis to provide a positive stop for the blade, said angle being of a magnitude to insure contact with a face of the edge facet or with a junction point between the facet and the blade, thus protecting the edge itself from damage as advancement of the blade is stopped by contact with said contact member, said contact member being mounted to a support member to form a two layer laminate, and said contact member being made of a hardened material to limit mechanical wear and damage to said support member by the blade as the blade contacts said contact member.
