If you have like me, a nice collection of multi-meters, you probably also have a lot of probes. I like testleads that have bananaplugs instead of permanent probes. This way I can use them with probes, crocodile clips etc.
I kept them in a drawer of my desk in a box. I like sharp probes so it was not always a good idea to try to find them without looking. A piece of wood and some drills is all you need.
