ABSTRACT:
A portable knife sharpener comprising two duplicate bar or narrow plate-like clamp members connected together adjacent to but spaced from their one ends for pivotal movement about axes generally parallel with the planes thereof and having facing planar surfaces with linear edges at their ends closest to their pivotal connection. A thumb screw is threaded in one of the clamp members intermediate its end opposite to said one end and its pivotal connection with the other clamp member the end of which clamp screw abutts the other clamp member. A discrete flange or angle-like member is pivotally connected by one flange part thereof to the side of each of the clamp members not facing the other clamp member with the other flange part of the member extending normal to the planar surface of the clamp member to which it is connected. Each of said angle-like members has a plurality of apertures therein spaced like distances from the planar surface of the clamp member to which it is connected. In one embodiment apertures are laterally offset from the clamp member.
