A recent self-challenge project:
The handle is made of coat hanger wire, the rest is a slightly thinner wire. I made a simple jig--two screws screwed most of the way into a block of wood--for making evenly-spaced bends. After bending, I used pliers to tighten the curves a bit. I also used a metalworking file to round the ends of the wires. I used sandpaper to grind off some rust; I should have done that step first. It works well enough, although there are some slight modifications I would make on a second try.
