Is that like snapon and the symbols?....... odd...@3baygarage thank you for sharing that! I have no idea what those symbols mean, but interesting to see that such symbols existed.

Do you have an example photo? Every time I have seen a Ko-ken extension in a non-official photo or video, they shaft is brushed chrome. I think the only ones that are satin on the shaft are the very shortest extensions or the extra long extension sockets.Are Koken extensions with the heavy knurling on the drive end satin finish or polished? Some pictures they look on or the other but the part numbers are the same.

So it's a fairly rough surface? Not a criticism that's what I prefer. As for brushed vs satin I can't find much difference. I know brushed is basically parallel scratched in a chrome but how do they achieve the satin?Do you have an example photo?

The brushed texture is pretty smooth and looks shiny at a distance but you can see faint lines up close and feel a slight catch on your skin. It also doesn't reflect quite like a polished surface. Maybe more obvious on the larger diameter extensions.So it's a fairly rough surface? Not a criticism that's what I prefer. As for brushed vs satin I can't find much difference.

I would describe them (certainly mine) as polished.Are Koken extensions with the heavy knurling on the drive end satin finish or polished? Some pictures they look on or the other but the part numbers are the same.
I really like OEM Tool's socket design.
I have a few very old S-K sockets with a ring of knurling around them and find that helpful. I wonder why that feature fell out of favor?
Thanks for taking photos i appreciate it the work. Especially comparing it to other finishes.
Deep knurling isn't easy to mass produce so I assume that's why most manufacturers don't go for that.No idea. Hazet still does it as does OEM Tools. REAL knurling, not the just cosmetic stuff, and in the right place on the sockets. Ko-ken sockets would be perfect if they added a band of their excellent knurling to their sockets.
To answer the original question that was asked in the first post. Nothing in particular than I've seen. They make sockets and they make ratchets. I find neither of these "special." Their tools do turn nuts and bolts just like Gearwrench, Williams, Proto, Nupros, Hazet, Gedore, Stahlwille and every other ratchet or socket I've ever used. Call me jaded if you must.
2nd Gear. You mean the HIGH price? Well, if that's the criterion for making something "so special" we're kick their Japanese asses again: WE HAVE SNAP-ON. Take that losers.
Their Zeal sockets have the absolute lowest tolerances I’ve ever experienced.
Craftsman socket on a Craftsman ratchet: might as well be a wobble set up.
Tekton socket on Tekton/Capri/Icon/Snap On ratchet: better but still a lot of lateral slop.
Koken Zeal socket on any of those ratchets above: barely any slop.
Koken Zeal on a Koken ratchet: be prepared to have your garage filled with the golden glow
venly light, soft harp music and a few doves flying by.
Hell, a Tekton socket on a Koken ratchet is very good too.
The anvils on Koken ratchets have extremely low wiggle. And as everyone express here, the ratchets have insanely low back drag.
The only complaint I have is the comfort grip on their ratchets are too short in length for my XL hands. But their non comfort grip ratchets are incredibly comfortable.
I love Koken tools.

NO, I don't. And don't need any either. I will admit do have a personal grudge against Koken. At SEMA they asked me to carry their products and I agreed to do that. Three weeks later I ask them what the deal is, no reply. A month later they tell me that they changed their mind. Well **** 'em. I've got all of the TOPTUL sockets I'll ever need in this lifetime and likely the next and they have never failed me. Other than their ratchets, which people claim are wonderful, how much more wonderful does it get compared to Snap-On and Matco particularly with the flex head which is what I primarily use. Frankly, I like the ICON 3/8" long flex head A LOT. I do have a Nupros ratchet and it's very pretty. I don't know if it will turn a nut or a bolt better than anybody else's ratchet and since I have about 8 cordless Milwaukee ratchets and I've just bought a DeWalt 12V extended ratchet just for the hell of it I don't use regular ratchets all that much. And, as I've mentioned many times I have a great stash of original Williams, when it was an independent company and not part of SNA, B52 and B54 ratchets which I still maintain were the best ratchets ever made.I wonder if Denny owns any Ko-ken sockets/ratchets![]()

Were you speaking to Ko-ken (the Japanese company) or "Koken USA" (the independent dealer, same operation as palmac.net)? I'd bet it was the latter.At SEMA they asked me to carry their products and I agreed to do that. Three weeks later I ask them what the deal is, no reply.

Depending on what you work on: nut grip sockets, particularly 1/4 drive swivels for hard to reach items. their wobble plus type extensions with the ridges of knurling around the female square drive end are amazing. if you have a need for super short sockets, look no further than the Zeal shallows in 1/4 & 3/8 drive. Their attack driver hand impact driver is worth a look. I'm fond of their spinning cross wrench for changing tires. Yeah, a cordless impact is quicker but, also takes the fun out of it. Spark plug sockets with the integrated extension. Deep Nut Twister impact sockets for removing damaged lug nuts. Quick spinner adapters. you can go from 1/4 square drive female to 1/2 drive male with a nice knurled ring in the middle. They've recently expanded their 72 tooth ratchet selections adding 1/4 & 1/2 drive with quick release options. Some peeps rave about their low back drag and they probably have the lowest back drag of any ratchet but, I find their ratchet heads to be on the thick side, and their comfort grip handles on the Zeal series should be longer and narrower but, that's just me. These are my Ko-Ken favorites off the top of my head.theres a couple koken sockets I need. Since I’ll be buying some stuff, I figured I’d look at the rest of their catalog for interesting things.
most of this thread is 10 years old. Is there anything these days in 2023 that koken makes thats still unique and worth looking at for someone who already has standard tools from quality tool makers?

one alibi: the 1/4 drive flexible extension bar is a work of art.
