Two small-ish axe heads made during a weekend tomahawk making class at the Brookfield Craft Center with Joe Szilaski. Dude is amazing at what he does, and is a very capable instructor. The head on top started out as a railroad spike, and judging by the sparks made while grinding, it is maybe a medium carbon steel.
The small bearded axe head started as a piece of W1 steel 1"x1"x4" and took quite a bit of time to make. I had never made an axe head with such a dramatic downward swoop of material before this class and learning how to do that was great fun. Lots learned about how to move the metal where you want it to go.
Both have yet to be brought down to a sharpened edge and heat-treated.
