16th Century Dusack (Dussack, Tesak)

[Triarii]

There are people making very nice repros of these, and other swords with exquisite detail to the hilts, but the one I know is a bit of a one man band from the Czech Republic. I have a simpler one.

However, the blade on yours certainly looks original, though the hilt has been well cleaned.
Older swords generally show hilt wear in two key places which matches experience of carrying reenactment swords; the top of the pommel, where a hand often rests on it, and the inner edges of the guard, where it rubs against the waistbelt / baldrick and your clothes.
