One letter. One number. That's the whole system.
Label drawers, totes and cabinets with one letter and one number: M3, T8, G2. The letter only has to make sense to you.
Things in the same container do not have to belong together. Mixed drawers are fine. That's the point.
“Put the rivet gun and leather punch in M3.” She writes it down in your words.
“Zita, where's the leather punch?” — It's in M3.
This is the one rule that matters. When you're done with something, either put it back at its address — nothing to say — or tell Zita where it went now: “Move the rivet gun to T4.” Her records and the shop have to agree.
Hooks, shelves, walls, the pegboard: just describe it. “The framing square is on the hook beside the table saw.” No numbering required.
Active projects stay out and don't get recorded. An unfinished project you've stopped working on goes in a bin, the bin gets an address, and Zita records the project and its parts: “Put the unfinished lamp project in T7.”
If you call them grabbers, they're grabbers. Zita doesn't rename your tools and doesn't invent categories.
You never have to inventory the whole shop. Add things as you come across them.
