looks like Esco is the original manufacturer (press 1 for English)

Perhaps they are the original (AI didn't seem to think so but there was no proof I could find in the links) but as I mentioned, they don't make an SAE version.

If you get around to testing on a 1/4-20 or M6 let us know how it went

I did find this video where he cuts a 1/4 - 20 bolt. Obviously takes more effort but it seems to work.

Sorry for crummy photos.
raised center, reverse reads "drop forged JAPAN", curiously JAPAN is(rather lightly) stamped not forged in as all the other markings.
Only example of the brand I can find.
Thoughts? Maker?

Possible Asahi? The font reminds me of them.

I came across a Vessel Cushion Grip #2 crosspoint screwdriver, the regular cushion grip, not the super cushion. Apparently they stopped making it in that size as it’s no longer listed. Anyone know when and why?

I found a Japanese cutting tool mnfr, Ishihashi Seiko, but their logo is vastly different and I see nothing but cutting tools offered.
Has anyone seen this brand before?

New machine screw cutters from Engineer.

No SAE, and no M3.5 for European light/socket face plates.

Exactly like the above one just with one extra hole, oddly.

The super cushion (gel) screwdrivers replaced the cushion screwdrivers. When, maybe 5 - 10 years ago. (just a guest)

Have some upcoming automotive work coming up, so no better reason to order tools! Also Japanese tools for Japanese trucks just seems correct. By one of the photos I suspect you'll know what brand I am working on.

First up is items from KTC. The black pry bars are brake adjusters. The little spring clamp looking pieces actually clamp onto the door switch that controls the overhead light. Lastly the blue brush is just for cleaning up afterwards. I like having one by the project sink.

Next up are 3 different kits from Tone. I've been wanting to try out a ratcheting screwdriver. The little black kit will live in a truck for swapping batteries. Lastly, the 1/4" hex drive was a bit of "I know I don't need this, but until I purchase it I will feel a void in my life that only this tool set will fill". Sometimes you just need a fun tool and they call that color of case raspberry which adds to the fun factor. You can also get the get in a black case.

Most of this stuff is all stuff that I have seen before in this thread. I am looking forward to trying out the Eight Tool L-Keys. I am very happy with my Wiha L-key set, but those live in a dedicated travel kit. These will be more for bench work, and yes the SAE and metric have a similar "Magic Ring" to the Wiha. Also the auto punches are much more comfortable in the hand than what is readily available state side. Lastly, the narrow needle nose pliers are a second pair because I find that I use them enough to justify.

Moving into long items and Koken stuff. All the red Koken boxes are for pulling studs or installing studs. Interesting to me is all the latches on the boxes are different. Does that matter? No, but just a little random detail thing, yes. Also the Koken ratchet is my first from them. I understand why they get so much praise. Its very smooth! Like I wish I hadn't bought it because the evil thought of have at least one in all the sizes has entered my mind. The only thing that surprised me is I find the handle small and this is coming from someone that wears a medium glove. I prefer the Tone oval handle. Speaking of handles the knurled handle on the Koken breaker bar does get a thumbs up from me. I choose that one because if I am using a 1/2" breaker bar I don't want it slipping in my hands.

Next up is items from Koto and Hasco. Both brands I've not seen much or anything about. The puller is a pilot bearing puller. The bottom pliers are for C-clips for drum brakes. The top pliers are for electrical connectors but the jaws can be adjusted. From what I can tell is Hasco is more for semi-trucks and box trucks and not passanager vehicles for the most part.

I did the dangerous thing of seeing if I could get physical catalogs, and succeeded for some of the brands. Sometimes I just like a classic catalog. I also learned KTC makes a small selection of dental tools. Who knew!

Last, but not least is I think I found Toyota branded Koken sockets. I have heard Toyota is starting to switch over to them for some of their tools.

They still have some sizes in their current production, so I assume only part of the line was discontinued?

Nice!

Those Tone bit ratchets have been of interest to me for a while. Obviously made in Taiwan (or at least the ratcheting mechanism is) but a longer handle than most. Good for access, if not leverage.

The KoKen roller stud pullers are the best I have used. Nothing grips as well, with so little damage. One of their “stand out” tools I think.

With regard to the ratchet, bear in mind that is a Z Series ratchet, so they are supposed to be compact!

I've been pleased with the Tone ratchets overall. I have been filling out the collection with the different drive sizes and fixed head vs flex head. I would say they are a good value especially in a non professional setting, but would be reasonable in a professional setting.

Oh, good to know on the Z series ratchet. Thank you for pointing that out. I need to spend some time in that Koken catalog and do some research.

I'm excited to give those stud pullers a try. In your opinion/experience is it a remove stud with the understanding that the stud will be replaced or reused? I don't mind replacing, but just helpful to know if I need spare hardware on hand.

What's the pink handled KTC tool above the spring hook tool?

@Bad Mojo -
where did you source the little "Kurokin" adjustable from?
That one was bought from Yahoo Shopping Japan. I did use a shipment forwarding company to handle the shipping. It looks like it available from Amazon state side. FLS-43-BG is the model number.

It is a brake shoe spring holding tool. ABX-33

I would totally agree!

Yes, the KoKen range is huge, and I’m not convinced many of the importers really do a good job of explaining the different lines. Always assuming they understand themselves.

The Z Series was introduced a few years ago to be a compact range of tools, specifically designed for working on modern vehicles / engine compartments, where space is tight.

Sometimes the gains are marginal, but overall they are there.

Worth downloading, or at least looking at KoKen.jp, where everything can be seen.

I don’t know what the original intention was, but I have certainly re used studs removed this way. I have also needed to run a die over a couple, and totally wrecked others!

I think you have the best chance with the “deep socket” style, as the contact area is so long.

But ultimately they wouldn’t offer the threaded style “stud setters” (which I see you also have) if the roller style never damaged a thread!

A good friend gave these pry bars a few years ago and told me they were Japanese made, but they were so filthy I couldn’t find any sort of manufacturing marks until I finally cleaned them up today! They seem to be of high quality: the bigger one was abused rather hard by me, and the edge of the chisel end of the big bar reflects the damage, but I had to work at it

Should this be in the old tools section or the Japanese tool one? Any guesses as to the manufacturer?

Thanks y’all!1781993904130.jpeg
