Every single positive review of a tool box talks about the thickness of the metal as does every negative review. I can't think of a tool box review that I've read that it wasn't discussed at all...
That's insane. The thickness of the metal is important to pretty much anyone looking to buy a decent box. I mean I don't know the exact gauge of the metal, but I know that it's stout. I don't know the exact weight of the box, but I know that it is pretty darn heavy. and I wouldn't want one with thin metal and that I could pick up with ease because I don't believe it would hold up to being filled with tools.
I suspect the author cast a broad net on the audience of Tool Box Buyers.
Walking through our Shop I see every kind of tool box imaginable. And I would say 90% of my shop bases their Tool Box purchase on only 1 thing: Price. I asked a few of the low price box owners and none of those I asked based their purchase on Material Thickness or Tool Box Weight. Now those I asked who have "invested" in a Tool Box, ie: Kennedys or upper end Craftsman did consider the, for lack of better words, "sturdiness" of the tool box.
I think the GJ audience would require a much smaller net with finer holes and thus why we come here.
I transitioned out of upper end Craftsman Tool Boxes to Mac Tool Boxes. Solely based on overall quality, Drawer Slides, stoutness, Casters, Drawer Size selection, height, width, depth and function of the storage system. At the home shop I have 3 Macs, MB1902A topped with a MB1910 in the Car shop for Automotive Tools. In the Machine Shop a MB1350 for Assembly Tools and an MB8800 for all Machining related tools. Still have a Craftsman Professional Roller Chest for all my Armorer Tools and a double wide Professional Upper Box for End Mills, Drill Bits and Lathe Tooling (Drawers are lined with custom made Aluminum Trays with moveable Insert Dividers).
In our Fab Shop we have tried Lista and they will not hold up to the amount of Turret Tooling we need storage of. So I design the storage system 20 years ago from 14 ga and 16 ga CRS and heavy duty Drawer Slides. It is an add on system. When we run out of space we just make another run and add on. The Drawers are design to handle the load as if they were loaded with a solid steel bar the size of the Drawer. Not one failure in 20 years.
There is a difference between "
buying" a Tool Box and "
investing" in a Tool Box. I'll make the assumption most here on GJ invest.
