I was able to re-harden the hook and get it too work later on, but not bad for a piece of car spring i got for free.
The start: two car springs
unwinding in the forge
Left: forged blade
Right: grind put on the blade
heating up to curl the blade with a hammer
sadly i forgot to take photos after this point as its very fast work and i need full concentration to get it right. I have to say making ones own tools is a great experience and it gives a great feel for the craft at hand. still have another hook to make so when i get chance will have ago.
