The threads were pretty old though, what do you think they couldve been

Also located on the Ashi of my sword is a yellow thread which was also previously on the Kabuto gane but fell off, does this mean anything. I know its not an official tassel or anything.

Also on the leftside of the Handle it looks to be signed or something but it is scratched out

I have Different numbers 0 3 1 or 1 3 0 stamped on them

sorry for the spamish posts, i have no clue how to properly take photos of a hamon line

I can try but im pretty new at this, ill post it in about an hour or so when Im free

I recently received a sword from my father who received it form my Grand uncle before he died. It is a Kai Gunto. It isn't stainless steel because it rusts, and I have a signature. However I don't exactly know what kind of steel it is made out of. Would it be possible to find out what kind of steel it uses .
