I'll admit that I don't utilize my main box in the shop as much as I should since I have a pegboard, I have utilized the top of this box and the tray even less than I do the box in general aside from all the pliers in the bottom drawer.
Hell from the day my dad brought it home from my grandfathers shop when I was 7 the top was never opened till my dad gave it to me about 10 years ago.
I'm starting to rethink some things and wanting to really set this box up better, so I reorganized it yesterday and today I found a better place to put it so I can actually get Into the top.
I set the tray up as a good basic 3/8 and 1/4" assortment I can easily grab and work from as intended, it'll probably be the first time that tray was really utilized since my grandfather was a routine service tech for the local Highway patrol station back in the 70's.
