Neil -

The blade is absolutely square to the holder and the final edge is square to
the side of the blade. I have tried to apply pinpoint pressure to the right
side of the blade as you suggest and although this helps, it's kind of hit
or miss. It most often results in a MB that's kind of barrel shaped, with
the right and left sides being deeper than the center. I'm starting to
wonder if the tool holder may somehow be out of alignment, even though I
don't have super accurate way to measure this.
