Most people have to keep track of at least a few keys. The easiest way to do that is to just keep them all on one key ring. But the more keys that you have, the more they fan out on the ring. If you have a lot of keys, then your key ring can get pretty bulky and impractical to carry in your pocket. Here is an alternate design for holding and organizing your keys that is a little more efficient.
The design of this key holder is very similar in construction to a Swiss Army Knife. The keys are arranged on two parallel bars. Each key can be rotated into the handle for compact storage and rotated back out for use. So here is how to make a Swiss Army Key Ring.
Step 1: Materials
Two pieces of wood (about 1" x 3.75" x 1/8" each)
Thin sheet metal (about 2" x 3.75")
Two #8 machine screw lock nuts
Two #8 machine screws, 3/4" long
Ten #8 machine screw washers
Glue that is able to bond wood to metal (not pictured)
Wood stain (optional)
Drill and bit set
Sand paper/sanding block
Small binder clamps
Paint stir sticks are a good size to be used for the wood pieces. These are generally free at the paint section of most hardware stores. For the sheet metal, I used a baking sheet that I found at dollar tree for $1. This yields about 13" x 9" of metal.
