Claim 0:
1. A tool box for removably receiving a plurality of hand tools, the tool box comprising:
an enclosed chamber for holding a plurality of hand tools, the enclosed chamber having a bottom functionable as a floor pan and a plurality of upstanding sidewalls extending upwardly therefrom to define an opening at the top of the enclosed chamber;
a lid removably for covering the opening; and
a plurality of N monolithic trays, vertically stacked from a bottom monolithic tray to a top monolithic tray, each of the N monolithic trays defining an XY plane at the bottom of the tray with a first surface and a second surface opposed thereto, and defining a Z direction perpendicular thereto, each monolithic tray further having at least one pocket in the first surface being configured to securely receive a complementary hand tool therein, each monolithic tray further comprising at least two posts upstanding in the Z direction and being spaced inwardly of the sidewalls to have a space therebetween and to form an irregular pattern with, each upstanding post intercepting and being received in one of at least two sockets disposed in the second surface of a superjacent tray stacked monolithic tray whereby each superjacent monolithic tray can intercept upon the posts of a subjacent monolithic tray in succession until the top monolithic tray of the plurality of N monolithic trays is reached and that a particular monolithic tray can only be disposed in a single, unique configuration relative to the sockets of the subjacent monolithic tray, whereby each monolithic tray of the plurality of monolithic trays can only be loaded into the stack in a single predetermined XY orientation relative to the other trays in the stack.
