There are lots of different hammers, but I’ll show you 2 today.
The chasing hammer has 2 sides. The bigger, wider end and the smaller ball end. You can use this hammer to put marks in your wire. You can use the larger side to carefully harden your wire designs with minimal marks (although I would suggest you use a nylon hammer instead). The round side is great for making cool marks in your jewelry like I did for these Hammered Wire Earrings.
You can also shape and bend sheet metal with this hammer.
These hammers are used to harden wire and wire worked designs without marring the wire.
You’ll also need a steel block or an anvil to hammer on. You can find these where jewelry supplies are sold and in different sizes. I got a tiny one with one of my hammers which would be okay to start with.
I hope you’re ready to do some hammering now!
