Hi guys! I'm quite new here, so please excuse the Nihonto noobiness.😀
So my uncle has what he believes to be a WWII-era Japanese sword (it's been stashed away for decades in his closet). We took off the handle, and expected to find an engraved signature, but instead found what appears to be the letter "T" written in sharpie. I guess that means it's not authentic, but I just wanted to get some additional opinions from you guys to be sure. Any information would be greatly appreciated!
P.S. Sorry about the unprofessional pictures! I took them before I realized the general Nihonto protocol for photos.
