This is a simple chain that requires very few tools. Bonus points for recycling wire!
Step 1: Tools and Materials
At the very least, you will need a pair of pliers with a set of cutters. It this demonstration I am using a pair of snips, round nose- and flat nose pliers. I also use a jeweler's ring mandrel in the end, but anything round will work.
You will also need wire. I'm using 12 guage aluminum wire that I dug out of my scrap bin. You could use any type or size, however.
