I like this project because the process is fun, the product really is useful, and it's a simple way to get to know tool steel.
(It even includes some blade making techniques!)
I used a piece of old bandsaw blade, 1in wide, which was too chewed up to be repaired. It's good steel - springy but holds an edge (see: SAW.) And this material is FREE if you know where to look.
I like to sew, so the seam ripper is a must for cutting out stitching mistakes. Nice to make my own.
I made this at TechShop Detroit. I'm a big enthusiast. Here, check it out: www.techshop.ws
