From what I saw, it is just a push block with rubber on the bottom. I
gather there is more to it than that.

Most of the push blocks I have I push to the side, or push forward.
With the Gr-r-ripper, I can push straight down, and feel very
comfortable doing this.


Yes, I could make lots of push blocks with slits and holes, but it's
easy to just shift the middle pieces to the left or right to match the
cut I am doing.
