Another thing to consider is just how many tools are on your inventory. How many of us carry tools that we never or very rarely use? Personally I have shadows for some items but wrenches for example are held together with a carabina type clip so i can do a quick count. Screwdrivers can be bought in sets which come with a plastic wall mount that will just sit flat in the box, easy to see if ones missing, the list goes on...
