I made these lil fellers justa c how they would work. The blades are jigsaw blades that I shaped the way I wanted then I heated them red hot then dunked em in used engine oil. Then I heated them blue hot “right before red hot” then dunked em in water. I used a dowel cut in half lengthwise, drilled a hole the size of the dowel and glue or epoxy to hold the blade in the handle. If you have questions or a cooler way to make em, let me know!
