A video came across my news feed of a similar project and decided to try it myself.
The starting piece, a 2.25lb axe removed from the handle.
I’ve lightly marked the cut line with a tungsten scribe.
*note the relatively clean shop floor.
An hour of cutting later. . .
I made the back a little more geometric.
I need to do a bit more cleanup on the cutout, but it’s coming along nicely.
