Drop by any machinist’s shop and you’ll more than likely run into the Kennedy 3611 or one of its little siblings. Machinists have favored these boxes — and other manufacturers have copied them — since Kennedy started making them in 1910.
The 3611, one of the larger boxes, contains eleven felt-lined drawers covered by a front panel that protects and secures your tools. The front panel stores in the slot on the bottom of the box until you need to lock things up. You can lock the upper center drawer independently of the other drawers.
The Kennedy 3611 sells for about $500.
