forgive me but apprentice auto mechanic thats funny. i been turnin wrenches goin on 30 years.
i speciaize in trannys and honda makes tubes in there trannys with built in sreens. there kinda small but make good one hitters. also them sockets you cant find a use for, well stick a screen down in a clean one and toke away. then you can just toss it in your tool box and it just disappars among the rest of your tools. for instance that 11mm deep 1/4 drive. theres all kinds agood stuff just layin around, be creative. oh and under no circumstance use copper.
