I’ve looking at toolboxes recently, and I’d be remiss if I didn’t mention the Henry O. Studley’s toolchest. Built in the 1920s, and designed to hang on the wall, it is 40 inches square and 4.5 inches deep when open (39 x 20 x 9 closed). Made of mahogany, rosewood, walnut, ebony, and with ivory and mother of pearl accents, it features fitted slots for each tool, and multiple lifting trays to store even more tools. (See video below for a better idea on how the tools fit inside.)
The part of me that loves secret panels and unfolding compartments, but I can’t help but think that it’s a bit cumbersome. To get to some tools you have to move three panels just to reach them. It’s more “art” than “tool”, but that does not diminish craftsmanship or beauty of the piece.
