Hello there. I am a rather casual sword collector, and have been recently been looking into purchasing a gunto or nihonto of some kind. I'm trying to shop smart, but also not break the bank, and I realize that this puts me in the crosshairs for scammers and fakes to sucker me into a bad purchase with an inauthentic item. I know the basics of how to spot an obvious stainless steel wall-hanger or modern replica, but beyond that I'm out of my depth, and could use a hand.
I encountered this possible shin gunto online recently from an antiques dealer who "is not a sword expert" (red flag thrown up instantly). The sword seems rather poorly made, which leads me to suspect it's just an old Chinese fake, but it's in pretty rough shape overall so perhaps that's just age and improper handling; I'm not skilled enough to tell. The tang in particular seems very bizarre to me with its chips and rough perimeter, and I'm not sure what to make of it. I personally don't mind the rust and damage since I think it gives it character, but if this isn't a real gunto I'd rather not bother. Would anyone care to give me their two cents? Thanks in advance! Pictures attached.
