dont forget to somehow marker/label all and i mean ALL of your tools. i used to work in a bodyshop and a few guys their sounded like your colleagues, used the crappy, over-used tools around the shop to take things apart n stuff, so i decided a small cabinet on wheels, with all my tools on it, gradually i had less n less tools, because some scroat was stealing them all the time and never putting them back, and once they got mixed in with the main batch of shop tools it was a nightmare figuring out what was mine, and even more so proving it when i left the business
