Hi Righthand,
I have seen couple of hammer bats, they are really good bats. But way over priced. I would put my money on a Bat maker like Laver, RobPack, Aldred or Red Ink. They are being made either in India now or from Affinity. as far as Bat making from hammer, have seen couple of makes from him on the videos but again way over priced for what you get. Personally, I liked the way Laver deals. I have bought 3 bats from him and till now, got maintenance free every year except paying for shipping.
