Luckily for me I learned that lesson without hurting anyone (it was a cheap-ish felling axe that the manufacturer had stepped the shaft on).
If the temper isn't ok, I do know a few peeps around the Mebourne-ish area who could probably re heat treat it for you - or point us towards those who can. Should be cheaper than buying a whole new axe.
