@glitterbag,
On the contrary. The Hardy Hole is a little square hole on the top of nd anvil into which a piece of hot steel or wrought iron is jammed in order to bend the hot metal or into which is put a steel chisel point that is used to cut a piece of hot metal.
I use it to make frog gigs which are like a small iron "forks" the tines of which are sharpened into points and it's mounted in a spear for catching bullfrogs for their legs. (Ill do that about once every 2 years when we get a hankering for frogs legs, then , if my son comes to visit he and I will go "giggin fer frawgs" . (Hes got 2 daughters)
OHYEH, the square hole on top of the anvil is called the Hardy Hole.Its little chisel must fit rather tightly
