Hmmm, I have some motorcycle wrenching buddies that prefer the Vessels over S-O PH tips. Not sure if they were comparing Instincts though. Did S-O design a new PH tip for the instincts?
not sure this are Japanese made but i bought them when i was stationed in yokota(air force), SK11 1/2D metric set. I really liked this set, never rounded a fastener with them.
It's really hard to find information about SK11 tools. The ones I have were made in Taiwan, but I believe they are distributed in Japan by the same company that makes Tone brand tools. Maybe one of those "domestic line" / "imported line" relationships?
My new Nejisaurus long nose pliers.
Fujiwara Sangyo was founded over 120 years ago in Japan. SK11 is just one of their house brands.
The SK11 tool lineup is round up by imports (European, American, Chinese, Taiwanese), Japanese domestic rebrands and non-rebranded Japanese tools. It's a mixed bag of stuff.

I did consider getting the neat little stubby oil-filter specialist 36mm x 3/8" drive socket as shown by Chris, but given I don't have a 'normal' 36mm and this was less than 1/2 the price, I figured it was OK for my once or twice a year oil change.
Once again, this ended up costing my about au$24, a chinese shop-brand 36mm 1/2 drive 12-pt socket is au$23 from Totaltools. I'll have the Koken thanks!

Typical beautiful Koken quality:

I have a 'specialty' lo pro oil housing socket for our M54 and truth be told, there is no need for it on that engine. Plenty of room up top for a regular socket, as a matter of fact I usually use a 6" extension with the lo pro socket to get more ratchet clearance above the engine.
And yes, the Ko-kens are really nice sockets!


This little KTC t-bar should do the trick for exhaust joint springs on motorcycles, and assorted other springs I've struggled with using the other tool.
It's a shiny black oxide finish, nothing elaborate but quite nice:

I realize you're in Australia but for anyone in the USA looking for this tool Harbor Freight sells this exact tool for $3.00 sold as a brake spring tool. I think I have about 4 of them and I use them for motorcycle exhaust springs as well.

Harbor Freight sell the Kyoto Tool Company AB-7 brake spring puller for $3 ?!
Damn, how does that happen? they're 1290 yen here in Nagoya.![]()
Koken Fail!
I got the last split shipment of my recent amazon splurge today. Koken hex driver t-bars in 4-5-6mm and a 3/8" drive T-bar (spinner type), plus a Hozan inspection mirror as shown off by superautobacs.
The hex drive t-bars are very spindly, not really what I expected. Not enough inertia to really spin anything in, nor enough strength to loosen or tighten anything significant. Nice, but for light duty only, which is OK but a bit unexpected.
Worst though is the lovely 3/8" t-spinner is faulty, the cross bar is not at 90 degrees to the shaft! I really did not expect that from Koken. It's still perfectly useable but certainly not what it should be. I'll have to see what the story is with rectification from Amazon.... ?? Anyone had any experience with that?

iv had little luck using japanese tools metal seems weak and cheap for my experience
The Japanese are well-known for their quality steel.

They're quite workman-like in finish, but have a nice action and come well recommended by those who use them far more than I will:

Really? I always associated Japanese steel to be inferior to European steel, and that's why they adopted their unique folding technique to produce Katanas. Obviously ratchets and katanas are little different, and a lot can change in a 1000 years, but my mind still makes that association for whatever reason. Maybe I am just ignorant.![]()

I'm a bit more cautious and tend to avoid things manufactured during the post-WWII US occupation of Japan.LOL!
Indeed, things have changed in the last 1,000 years. Some of the best tools I own come from Japan. Full disclosure though, I bought them within the last century...

Why? The U.S re-factoried & re-tooled them with the latest technology of the time. Then it wasn't long before they were teaching the world a thing or two about producing quality products...
My comment wasn't meant to be taken too seriously, hence the emoji I put at the end, but industrial production was down to about a quarter of pre-war levels when the occupation began, and manufacturers were resorting to reusing American GI's food cans as raw materials. The "Japanese economic miracle" didn't really happen until the early 1950s.Why? The U.S re-factoried & re-tooled them with the latest technology of the time. Then it wasn't long before they were teaching the world a thing or two about producing quality products...
There are only two countries in the globe that can press the highest grades of steel & they are Japan & Germany.
not sure why the US ain't in the game at that level but that's how it is.
There are only two countries in the globe that can press the highest grades of steel & they are Japan & Germany. Its been like that for some time although how that translates or effects hands tools is a different issue. But knives of the best nature will be made either in Japan or Germany. The machinery to produce such steel costs many many millions, not sure why the US ain't in the game at that level but that's how it is.

Nucor had to get a license from the Japanese to do a joint venture in steel production of Japanese style steel for construction beems. Nucor-Yamato is the name stamped on the steel beem which is about the best you can buy in USA. But as for tool grade steels American companies probably substitute quality for profits. Wilde is the only tool company I see in USA that has pride in what they make. Koken sockets make me feel a bit spoiled in that it is rare to see something in any price range that is as good or better. I have not had a chance to see wright sockets in person but proto or snap on are the only that I have seen that can hold a candle to koken or ktc. Even my sears wrench from Japan seems to hold up over the years. America did produce good things at OK prices before the knurled sk seem to be the best I have seen ever. But the days are long gone so kids be nice to grandad and raid the garage before grandma has a garage sale.Honestly do you have 1st/2nd hand knowledge of this? Charts and or figures comparing the top quality steel from producers such as U.S. Steel, Nucor, AK Steel, Steel Dynamics, ArcelorMittal and Kobe Steel will do. or is this just an opinion?
