hey I am new here and i have just purchased a carl henkel bielefeld long dagger off ebay. now that i have it . it seems like a reproduction because of its awsome state it is in and in fact that the blade is not sharp, it has a flat edge. i am not sure if they bade them dull. some of the pictures on here look like the same thing. is there a way to tell if this is original as I see no date?

thanks
-Jake
