I have to admit to being slightly puzzzled by what you mean by "testable".
If you're referring to carbon 14 tests and such, tests of this nature usually aren't indicated except in pieces of great antiquity, with swords in the 100,200 and 300 years being unsuitable altogether by being simply too new.
With wood, for example, what you will get is the age of the wood itself, not when a hilt was made.
