Shafts are .031 diameter steel. While this larger than normal diameter is harder to bend, it adds strength and extends the life of the lure. Beads, bodies and blades are all metal, nickel or brass, for added casting weight and durability.
Some beads are plastic for their color.
The dressed trebles are bucktail. The spinner is completed with a closed loop rather than a safety-pin and sleeve finish. This increases the overall strength of the lure dramatically. I started lure-making to provide myself with strong, quality lures that would hold up to constant use. Under most conditions the size of the lure should reflect the size of the fish.
