Got a mystery package this weekend, an Amazon package covered in Japanese writing. I had recently sent a pair of Tsunoda flush cutters to a friend as a surprise gift, so he sent me the Top HT-200B 200m/10" thin-jaw, offset-bend "Crescent" wrench! Neat!
24mm is as far as it will go. Not a bad idea, considering the thin and pointy jaws.
Here ve see ze life unt death struggle of ze two-part spring-loaded thumbscrew to prevent slop. Really impressed with how well this feature works, and the rest of the fit and finish is notable, too.
Sorry, no SAE markings for you.
Jaws are 4.5mm at the very tip, 4.8mm closest to the main body.
Take heed!

Some specs from the back of the packaging. At only 135 grams, HT-150B is probably a better one to drop on unsuspecting pedestrians if you're a practical joker.
Amazon shows this as a $39.60ish wrench today.
COO Japan.
It's also one item removed from my Harry Epstein's wishlist for July 4th. I had the smaller one on my list. I still have a very small one with very thin jaws on my wishlist.
