Who makes the Pro Sharp and how much do they set you back? I've got square chisel on the 660 and it sinks through the oak like it was melted butter. It is noticably faster than the round ground chisel I ran.
The Pro Sharp is Silvey's top square grinder and they are certainly overpriced because no competition. (around two grand).
They do have some cheaper models that some are happy with.
