I love the Hammerhead design. It is simply the best. And I have made Hammerheads from multiplex, noble wood, with a metal core, and got it made by Hogancastings in Aluminum and Bronze.
But there is one version that was left: A bent wire Hammerhead! So I started with an 8mm steel rod. Bent it into shape, welded the middle for stability, and welded onb some hex nuts as heads. Then, the absolutely necessary wrapping job, with thick 10mm paracord for the handle and regular cord for the fork.
Secured the cord ends with a bit of epoxy.
This has an excellent feeling to it now!
