Used that, the double universal version, plus zeal/nut-grip sockets for a subaru oil pan today.
Koken has been a real game changer for me.

Where can you buy koken in the US
Can't seem to find them, but there are no wobble-fix extensions from the Z-Series, correct?

Ah, i meant wobble-fix extensions from the Z-eal/Z-series line.
I don't think they're made; only regular, which should be fine.
Yup, no wobble-fix version in the Z-eal line.
When I was at a Factory Gear store in Japan, I made an indirect request to Ko-ken that they provide more variety with their Z-eal extentions (in between lengths and much longer ones).
One important tool I don't have yet. I've heard every impact screwdriver is basically the same, is it worth paying more for the Koken one?
They have 5 or so modelsDoes Ko-ken no longer flare out the grip on the impact end to offer some hand protection?

Are the koken Zeal 1/4 shallow/short sockets practical for overall use, or just for when one is dealing with tight clearances.
Looking at the height of the sockets, it seems it would make the ratchet sit a little too close to work objects to be used with complete ease. Does anyone find this to be an issue?
Looks like a tool polishing/drying tool to me depending on if your in the bathroom or garage.![]()
Is this considered a tool?
I found out that Ko-ken is one of the few companies that make short impact sockets.
To loosen some 19 mm bolts, in a very tight space situation, I ordered a Ingersoll Rand angle impact wrench. Unfortunately with the impact sockets that I have, the head of impact wrench doesn't fit above the bolts. So I searched for a shorter impact socket. I searched online, but couldn't find anything that would fit.
So I contacted the supplier where I bought the Ingersoll Rand wrench and they came with an impact socket set of Ko-ken. These are about 1.5 cm lower than what I have. Just got them today.
I tried and now I can get the the head of the impact wrench above the bolts.
The sets name is: RS14401MS/5 and I ordered it from Air Tools Emporium
Next weekend I will try the loosen these rusted bolt.

Probably doesn't help you in Europe, but Carlyle has shallow impact sockets in 3/8" and 1/2" drive. I know somebody else makes them as well, but I'm having a senior moment and cant remember who that might be. M7 maybe?
But I've been drooling over those KoKen shorties (and some thinwalls). I gotta quit looking through the KoKen catalog on my computer...


Thanks Reed Prince - Yes, those do look like quality hinge. Foam inserts look quality as well. Nice stamping of the lid - reminds me of the "old school" boxes you used to be able to get before most went plastic.
It is interesting that your first pic appears to be the same set as my second pic but the box stamping in the lid is different. I wonder which one is current?
Stamping is actually on the same side/orientation....just gotta rotate you head 180*.![]()
see 3286 in my photo and then the later one, one has a smaller script in the corner too that appears to say Ko-ken Tool Co. LTDI'm pretty sure the stamp in one of the photos I posted is more in the center of the lid, Chris?!!?![]()

Is there anyone in Canada selling Koken?
Have you checked out the possibility of ordering direct from Amazon Japan? Lots of folks in the USA have reported that Ama JP's international shipping is reasonably priced and amazingly fast. Good luck!
You're right; my bad!
I'd guess that the off-center stamping is the more current one:
