I had an old butcher block of wood before I got the granite base and it was not good…it moved around too much during the process.
I used an old rock maple 12×12 cutting board for my base. It is about 2″ thick. I glued some adhesive rubber pads to the bottom to provide stability – and it works very nicely, even though it is relatively light weight.
Gotta love Paperstone, though. It is made from phenolic resin, and is basically paper micarta – just without the Micarta trademark. There is another company named Richlite which makes a similar product. I’ve used 0.25″ samples to make knife scales from – and Buck is using it for scales now too. Good stuff.
