The 1/4" body part numbers always start 272. The 3/8 drives in 1/4" bodies always end in -3/8. For example, a non-flex head will have a part number 2725Z-3/8.
this is the newest zeal section of the catalog (dated april 2023). notice all the quick release variants.
i wish they had a badge that showed you if it's a 3/8" in a 1/4" body so you could tell that a glance.
they should have that next to the other badges. the only way i see to tell is to look at H (9.5mm vs 13.7mm).
Thank you for sharing the pdf!
The quick-release button shape is a little different between those two body sizes; 1/4" body with 3/8" square to the left, regular 3/8" to the right.
I was hoping to see one of those too.So many 3/8" in 1/4" ratchets but no still no 1/2" in 3/8" ratchet
Although the full size 1/2" quick release does look pretty nice!
Shinwa are one of the better known Japanese rule brands. The bigger / better quality rules are made in Japan, but the cheaper ones are made in China.
Very interesting!

I have some rules by Minemura, which are all made in Japan, and one by Fisher, which also is.
A local woodworking specialist always keeps a selection of these rules in stock. The actual makers seem to vary, but the quality (and style) does not. All are made in Japan.
@Loga_3, I looked up both your and my rules in the Shinwa catalog. They are both made to JIS Grade 1, and can be certified via the Japan Calibration Service System. It looks like Shinwa is keeping their overseas models up to good standards.I just bought a 30cm one, which was supposed to be made in japan according to all the sites i read it on, buuuut no. China.
However! The quality is superb, even thou its made in china.
I wonder if the anvils in the existing 72t ratchets can be swapped with the new quick release ones?
I just picked up a set of these. I’m very impressed. Although some of the smaller sizes are overkill for torque. Careful tightening those 10mm bolts! lol. I can see them being great for access as well like deeply buried dash bolts.Really liking the finish on these tools. May be time to add some German to the mix.

Getting those back in may prove the challenging part
knowing Koken and their attention to detail, I can almost guarantee they can be swapped just like the 72t anvil. also judging by the videos and presentations they look identical, it makes sense for koken to not design a whole new mechanism just for a quick disconnect.
No experience other than fiddling with one at a store.
