Here's some hooks Nigel and I made last year.
They are fun, but I won't presume I know enough about forging to instruct anyone.
However, I needed some matching fasteners. Rather than make some screws from scratch, I bought some standard machine screws from the hardware store and put the heads in the forge. Heating them up red hot and then bashing them around with a hammer gets just the right look, while the other end remains unchanged. The hooks and screws are then warmed with a torch and painted with beeswax.
They have been hanging in my kitchen for almost a year now, no noticeable change in finish.
I'm interested in making more, contact me if you'd like some.
