I refurbished a cheap old axe/hatchet from the hardware store that was hiding itself in my garage for quite some years. It took me several angle grinder discs, loads of elbow grease and almost one year of time (since I didn’t have the time to work on it consequently).
I gave it some kind of a “viking” oder “northern” beard-axe form, as well as a new self made handle. No fuss and no decorations for the first one – it was an experiment – but a veeery sharp edge 🙂
