I have a stackable box. Sockets and ratchets on top. I have a September drawers for allen wrenches, screwdrivers, sae wrenches, metric wrenches, pliers, hammers. Bottom has a drawer for filter wrenches and specialty tools, electrical stuff such as meters. Drawer for wood stuff such as drill bits...
Me and a buddy built some bikes in the early 70s that we rode on the local motorcycle trails. We were doing it before it became popular. Then we got motorcycles in 74 and never looked back.
