This is a public thank you to Roger at hizento.com. I sent him a picture of a Tadayoshi Mei that I suspected was gimei and he kindly took the time to confirm it and respond back very quickly. I had hoped that it was genuine, due to the care that was taken with this blade over the years and the fact that it was housed in an older, darkened shirasaya. But, alas it was not to be. While it is a nice old blade in fairly decent polish, it is a fake signature. Thanks again for being so kind Regards Scott Enloe
