BB pal Adam Savage of MythBusters liked using antique leather doctor's bags to hold his tools. But the bags couldn't handle the 50+ pounds of tools that he needed while working at Industrial Light and Magic. So he remade the bags out of aluminum and added scissor lifts for easy reach. "The finished boxes housed everything I needed, but I repeatedly rebuilt the insides until finally no tool had to be moved out of the way to get to another," Adam wrote in Wired. "That's first-order retrievability."
