I'd say the single largest factor is that we need to have full SAE sets in three drive sizes while most of the world doesn't need any SAE tools at all.
That really is the answer right there. Bigger shops, bigger pay checks, bigger debt, bigger egos.
I've seen guys with monster tool boxes, and all they do is PDI Chevy Cruze's all day.
American tool boxes are more often just storage containers for tools, and are otherwise useless. Just my opinion of course.
Take the box below for example...what the hell do you do with this? Lol

It's not just about hand tools anymore. Probably only 40% of my toolbox is hand tools. The other 60% is specialty tools and equipment, power tools, diagnostic equipment and measurement tools.
Most people have no clue how much stuff it takes to work on whatever comes through the door. They think they do but they don't.

That really is the answer right there. Bigger shops, bigger pay checks, bigger debt, bigger egos.
IMO, there is no reason why the average mechanic, regardless of country couldn't get along just fine with something like the KRSC46 but in a lot of US shops, the size of a mechanics tool box is somewhat proportional with the size of that mechanic's ego.
It wasn't always this way, but much more so in the last 20 years. It seems that new tools can not touch another tool. A metric wrench can't be in the same drawer as a SAE wrench and it is a major **** if you don't have a special drawer for your wallet, sunglasses and phone.![]()
Automotive techs can get by with small boxes. It's us DIY homeowners that need big boxes and lots of them. We have to deal with:
- Automotive
- Woodworking/Carpentry
- Plumbing
- HVAC
- Electronics
- Painting
- Machining/fabrication
- Various hobbies
- Welding
- Outdoor Power Equipment
- and the list goes on and on

I've never understood why techs have big boxes and homeowners have little boxes.
It's just a real estate issue.... right? Land comes at a premium in europe resulting in less space for monstrous tool boxes.

i like how so many want to pick apart the big-box owners. Sure i have one, and it's something i'm proud to have worked up to.....and i have never pdi'd a single car in my life
to answer the op's actual question, i like organization of the tools for speed sake, but i also think people are a little whacky that waste space with neatly laid out items spaced 4 inches apart. That's not my box. With the exception of my latest, which i did sorta buy just because i wanted a nicer box, i have only trade up / bigger when full and thing start getting too hard to find fast. Organization is a party of why i'm fast while my guys i supervise who refuse to buy more tools plod along at 1/4 my pace. Having every tool i need to do the work is also key. I don't really even care much about shop tools - i buy my own for all but the rarest used / most specialized. Being able to handle any job that comes in without going to the shop tools is, in my view, a guarantee for me that i will continue to always be able to earn that money - even if i left the company tomorrow, i can do just as good for the next employer, even if their shop doesn't own much for tools.
I also find it funny that most of the people i meet in the shop - customers, vendors and so on, all have positive comments about my big box. Things like "dedicated to the job" and "take pride in your work". I only see the negative stuff around here.
Sure, there are the squirrely 20 yo kids who show up with a big so krl box that's devoid of tools beyond what most could carry in a little 2 drawer chest in the back of their car...but the work usually weeds them out pretty fast. They either step up and get the tools to fill it and do the job, or it ends up on cl when they change career paths.
I've also seen a lot of old timers who stick to working out of a small chest / roll around - under 30" wide sorta thing. But that has only been in two type of shops: Strictly automotive where all they need fits, or some sort of fleet / gov't shop that has everything, even the small tools, to use from the tool room - no need to buy when it's available to use for free.
No doubt we are a consumer society - i think people spend their money in lots of ways i never would, but it's not my money, so i don't care.
It probably has a lot to do with employers in europe providing tools vs providing your own tools in america.
Two great points.. Being able to handle any job that comes in without going to the shop tools is, in my view, a guarantee for me that I WILL continue to always be able to earn that money - even if I left the company tomorrow

It's because we need both SAE and metric tools. Imagine how much all of us could've saved had we gone metric like the rest of the world?
Also, we are a consumer society. We like extra tools to make life more convenient. We could get by on less tools, but we don't want to.
I love the comments saying "a big box is compensating for a tiny ****"...I'd love to see you go into a shop and say that to a mechanic...

Well I am not normal English tech as I have 84 epic with hutch and a 54 inch 700 series and still need more space.
. You joined GJ in August of this year and you already made a clueless and idiotic comment amount another GJ posters tool storage system!
The sad part about you is that you pride yourself in being an A$$!
You ought to last a long time with that attitude. Are you on your 3rd or 4th stint? Or is it more then thatDon't read too much into my GJ join date, snappy-boy. I've been around a while. You've got bigger fish to fry, I'm sure of it. Like, how you're going to afford your next fruity custom colored behemoth tool showcase to impress your pals? Better get on that, junior.
Taking a dig at another mans tools, SMH.
