<p>A two-stage pressing operation for making a fishing lure from a sheet of form-retaining, corrosive-resisting, metal, such as spring brass, is disclosed along with the resulting lure. The original blank has a central portion and two semicircular end portions positioned with the circular portions thereof extending away from the central portion. First, the blank is pressed to form flutes extending lengthwise of, and for the full length, of the blank. These flutes, considered crosswise of the blank, are a series of convex suffaces of uniform width forming one surface of the lure blank and a similar series of concave surfaces forming the opposite surface of the lure blank, the latter surface having juncture lines between connecting concave surfaces. Thus, the central and end portions of the lure blank are provided with first concavo-convex surfaces comprising a plurality of side-by-side, parallel concavo-convex surfaces. Next, the end portions of the lure are provided with concavo-convex surfaces, with the arcs thereof extending lengthwise of the lure and at right angles to the first-mentioned plurality of concavo-convex surfaces. These concavo-convex surfaces, on the end portions of the lure blank, face in opposite directions and not only provide the lure with the desired action in the water but tend to cross brace the lure and make the same more rigid. Also, the latter concavo-convex surfaces can be added sequentially and the same will not substantially diminish the curvature of the first-mentioned concavo-convex plurality of surfaces.</p> |
