I spent all my summers as a youth, at the countryside, right next to a river. So obviously I devoted a lot of my time casting lures with a spinning reel. Pike and bass the name of the game. I am ashamed, that I never thought of doing this before. It's böhler "leuku" and uddeholm "crane" 30ish layers, only some showing. Heat treated and tempered. Half of the front side has the temper colour still showing, to mimic "belly and back" Slight distal taper from middle towards both ends, bevels only on the frontside. The backside has hammer finish for superior accented reflection action.
I got to try it for 45 min yesterday. Pike just love it! I got 2 and one flashed a stomack, no pics, they were too small, I let them live. The curvy shape and slightly offset hook, makes it swim and flow, ohh so, gracefully.
