Huh - so, they aren't really forged
This is a Snap On video about how sockets are made:

I've boiled it down to Snap-on and Proto. I like both very well, and they are the most durable of anything I have tried. I have around 550 unique Proto and Snap-on sockets, so I have an adequate pool to judge from. I've tried a lot of other brands, and from direct experience know that these two brands are up there at, or at least very near, the top.
I have not tried Koken, but have one ratchet I sought out and bought because SO didn't make it. It is the equal or better of Snap-on. I expect their sockets would be the same.
The guy that thinks Koken is poor quality because their stamping isn't as deep has posted extensively on this theory before:

It's not even a pro-USA rant??
Ko-ken are way better quality than Gearwrench which are an Ok starter brand in my opinion...
...i've used Koken socketry for 30 years professionally...
I’ve never heard of Koken before would they be good to try professionally I am in the market for some e-torx

Yup, Ko-Ken is hard to beat. Fit/finish, features/design, quality/strength, and price. Only downside is not super easy availability in U.S. For the warranty wonks here. . . warranty doesn't matter to me, I've never broken a socket.
MISSING SIZES. Only killer for me with Koken. What I would do for that 1/4 drive zeal 9mm and 15mm. Or you're using your nut-grip sockets for some strut mount nuts, which were 15mm, but are 16mm on the new mounts, and a different pitch so you cant use the original nuts. And yet, my set does not include the required size.
Eventually I'll wear the 1/4 zeal out. I'd happily buy a set a year at double the price for the hassle they save me.

I bought the nutgrips on your recommendation, they are a brilliant design and work perfectly. They really let you attack tricky jobs with confidence in restricted areas

Of course it makes sense. If they can save 10 minutes in the heat treating it increases production capacity with no impact on cost. What you're intimating is economies of scale, which is typically due to the cost of line changes. There's no cost associated with a Williams specific program in whatever software controls their heat treating process.
That Craftsman is impressively slim despite its age.Here's a couple of 3/8" drive
Craftsman USA, pre knurling 19.31mm late'60s or early '70s
Armstrong USA 19.85mm, likely one of the last to come out of that factory.
Good stuff. Thinner universal-joint sockets is further optimisation that makes sense. But it adds to costs. The thinner the wall, the more precisely centred must be the broaching.Samuel D: Here's some more data points; all 14mm:
1/4" Proto Flex Socket: 18.6mm
3/8" Snap On Flex Socket: 18.4mm
3/8" Proto standard 12 point 19.9
3/8" Proto H 6 point 19.9
3/8" Proto deeps, 6 and 12 point are also 19.9
3/8" Snap-on impact 20.3
1/2" Proto 12 point 20.4
Interesting that snap on flex sockets are thinner; the weak point on them is the joint,not the socket.
No, it doesn't make sense. There's a critical temperature that steel has to reach in order to recrystallize as austenite. If the steel doesn't reach that temperature then you haven't accomplished anything. If Snap-on had a faster way of heating steel to the critical temperature, they would use it on everything, not just on Williams branded stuff.
Williams is one of Snap-on's industrial brands. They aren't going to improperly heat-treat them, or not heat treat them at all, because industrial use is as demanding as, or more demanding than, the automotive use that the Snap-on brand is primarily marketed toward, and improperly heat-treated, or not heat-treated at all, sockets would hold up about as well as the cheapest, no-brand, dollar store sockets you can find. The first time you applied any significant amount of torque to them it would round out the socket's broached section and/or its female square drive, rendering it useless. That wouldn't be a wise financial decision, because practically every Williams socket they sold would come back to them for a warranty claim.
Want you just said amounts to “there’s only one way to heat treat”
which is such ******** that I’m not going to engage with you further.
You can go on Youtube and see how much Tekton ***** (unfortunately the answer is NOT that it doesn't ****, because it does, or at least some of their basic tools which need to have strength do ****). Had some other guy on another thread tell me that I don't know what I'm talking about because I'm "not a pro" and I'm "losing the forest for the trees" because I care about how much strength a tool has. The koolaid is strong with some people. I, too, want to get through jobs without having to go warranty a tool out. If you aren't buying tools because they are well-made and reliable, what ARE you buying them for? The trendy brand name that people are talking about online? Please.
Like here's one of many videos from various people you can find showing that Tekton ***** (this isn't my video):
He tests a bunch of underwhelming brands and Craftsman came out the best. Now, I've owned plenty of Craftsman and have personally experienced the open ends on those wrenches (USA made ones to be clear) slipping on bolts that better brands haven't. I consider Craftsman - literally every single thing they EVER sold - to be garbage, and Tekton is below it. Worse than garbage. Like I used to have Craftsman for just about everything, I'd use like their flare nut wrenches and I pretty much never got anything off without damage, whereas I have yet to have my Snap Ons fail at that, literally not even once.
So, yes, Tekton is the answer... to the question "What brand would I never, ever, EVER consider buying?" I wouldn't even buy Tekton for a tool I intended to literally use only once.
Like here's one of many videos from various people you can find showing that Tekton ***** (this isn't my video):
I'm thinking I'll go with either all koken or metric koken and sae williams.
I agree and think this bears repeating. Too often I see optional use of open-ended spanners. That’s bad practice.Open end wrenches are a last resort for situations where it's impossible to use a socket or box end wrench.
I have a set of Williams USA sockets in shallow SAE, and they are very nice. I would recommend them.
Where is the best place to order Koken products from without high shipping rates?

Ag and tools. Service truck, welding truck, pickups, flatdecks,. Triple bay box full of good tools for the stuff that the dealers wont touch and gets completely dissembled. Smaller boxes with medium grade tools for the guys that have no problem breaking 1/2 drive sockets and then there are the cheap tools that get lost out in the fields or rattle around in equipment boxes
