Looks like a decent reproduction. Is there a scabbard that comes with it? I'm not a fan of how the Bakelite grips look, but they appear to have a good fit. I am happy to see that this reproduction bayonet does not have a manufacture name or code on the blade.
It is a better than most reproduction.
As with all of the copy/reproduction/fake S84/98 III bayonets that have been made, you will see one on ebay listed as original. Maybe even have some wild story about the special marks on it meaning it was Hitler`s special KM bayonet he kept on the Bismark.
