Hi guys, I am totally new to world so please bare with me. My stepdad acquired this Japanese sword about 30 yrs ago from his grandmother after her husband passed.. which is not my stepdads blood grandfather...the sword was given to the grandfather by his nephew who served in WWII...anyway that is the history how we got the sword. Now after 30 yrs of sitting in a closet I was asked to learn what I can about it. If my findings are correct (which i have no clue if they are correct) this sword is Pre-WWII. The text on the tang translates as... omi no kami fujiwara tsuguhiro, so if this correct the blade dates back into the mid 1600s at the earliest and the early 1700s at the latest. I also understand there were two generations of smiths with the name tsuguhiro. It is my presumption this sword is from the 2nd generation because his work is described as being characterized suguha hamon which I understand is the milky look the the cutting edge of the blade takes on during the tempering process. Remember I am new and understand very little about this art so all is presumption. This journey at times has been overwhelming, so much to take in, but it has been very satisfying also.
My question to anyone who will listen is...PLEASE HELP!
