These finely detailed french blades are stamped from the highest quality brass sheet available and are designed to spin on command and provide maximum lift and thump! Buyer beware, there are cheaper and thinner imitations out there that will not perform near as well as ours. Also beware of blades that are stamped from steel. Our blades will feature the flashiest polishing and plating available. They are guaranteed to out spin, out flash and out fish all others hands down. Sizes #1 thru #3 are stamped from .025 brass material and sizes #4 thru #5 are stamped from .032 brass material.
