A fishing lure has a weak point so as to avoid losing the body of the lure if the hook of the lure snags a large submerged object. The weak point is in the shank of the hook, and it is provided with a parting strength that is less than the tensile strength of the line. Pulling hard on the line if a snag occurs causes the weak point to shear, allowing retrieval of the body of the lure. The weak point is a neck section surrounded by a groove, having a diameter less than the diameter of the remaining portions of the shank. The weak point is formed by a crimping tool which deforms the shank of the hook.
