Thanks again! what a great bunch of helpful people here. i have gotten help via post and email and within 24 hours!
i'll definitely be returning and (lurking) studying my new found hobby. beer and cheers for everyone
From my learning i say it: is steel, it has a shinogi WARE im assuming (its a small crack going lengthwise on the blade, you can for sure see a hamon, and it does look like it has grain and activity ( but nothing like what i see in some pictures)
i do have a picture of my grandpa and another solider holding swords like X and i have 6 years of love letter back to my grandma and in one letter he mentions the sword and mentions going souvenir hunting. im sure this isnt the forum for it but i have lots and lots and lots of wwii era stuff from Japan. ie. paintings, calenders, helmet(with blood stain on the inside), chemical suite, flags, the weirdest thing i have is a childs handwriting book (you know the kind that you trace the dots to form the kanji and then do it youself)
anyways thanks again, its been a pleasure!
