I ran across an auction of a set of Japanese bench chisels, and there wasn't a lot of info provided (and yes I bid because I'm an easy mark), so I'm trying to gather some details from the photos. The only visible markings are stamped on the chisel itself, and I'm wondering if anyone knows anything about it or has suggestions on where to look for further details.
Here's a zoomed version of the stamped markings with some photo sharpening:
I've sent a note to the auction house for more photos of the storage box or any other identifying info, but I haven't heard back.
Thanks for taking a look!
