Patent ID: 7278213

Claim:
In a folding tool having an elongate body and an implement, wherein the body includes two opposed sidewalls held in a spaced apart relationship defining a slot therebetween, the implement is rotatably attached to the body and is rotatable from a first position in which the implement is at least partially received in the slot and a second position in which the implement is at least partially rotated out of the slot for use, the improvement comprising: an elongate stop pin having a longitudinal axis, first end and a second end, a first cylindrical outer surface adjacent the first end, a second cylindrical outer surface adjacent the second end, and a central portion between said first and second cylindrical outer surfaces, said central portion defined by a plurality of planar surfaces parallel to the longitudinal axis, a first axial bore in the first end having a first diameter, said first axial bore extending partially along the length of the stop pin and terminating at a shelf, and a second axial bore extending from said shelf at least partially toward said second end, said second axial bore having a smaller diameter than said first axial bore; whereby said first cylindrical portion is rotatably received in a first cylindrical bore extending partially through the first sidewall and said second cylindrical portion is rotatably received in a second cylindrical bore in the opposite sidewall such that the central portion lies in the slot, the first sidewall having a hole extending therethrough into the first cylindrical bore and aligned with said first axial bore in the stop pin; and wherein the shortest radial distance from the longitudinal axis to each of the plurality of planar surfaces is different for each planar surface.
