It isn't, though Dave is a good friend of mine and I have... 5 other blades by him including a smallsword.
I purchased this years ago... I believe it was an old Paul Chen blade which was re-hilted, and I had rayskin added to it. It's held up REALLY well during some major stage combat work, but is quite hefty at around 3lbs. It sings when contact is made. Really happy with it though.
