I believe he uses Vic Firth sticks, but this is not VF. It doesnt have any trademarks at all. In fact, it looks like some kinda cheap made stick.
The seller has a bunch of items that look legit and this sig looks good. But like you say, sticks are easy to forge.
There are only a few good stick signers and they include Paice and Bruford as the best. And I have these 2. They can sign a stick just like on paper. That takes skill
