I wanted a hook knife for carving bowls etc and strapped for cash I contacted a riding supplies company and bought a "hoof knife" for £3.50 plus the postage...after receiving the knife I heated the blade and refomed it, then tempered and hardened it and hey presto I have a hook knife of my own making for less than a third of the price of a ready made item....
