I've had the pleasure and privilege to handle a couple of the Greek swords. They are wild. They have "weight" to them, sort of tip-heavy, but sort of balanced at the same time. It doesn't feel like a lot of weight is there / not very dense.
A good friend of mine went to a Burridge workshop earlier this year and cast 2 swords. They are pretty much dead-nuts on with the weight and feel as the artifacts. The ones that Matt Amt has made are damn close, too, but I'm sure you knew that already.
