Are the middle two blades there the RMD and the DMDC?
Yep. The RMD is not one of the new models, it's a bit older and the one
below it is the DMDC that I modified. Sanded off the Double Cut finish
so that it was nice and shiny, and put a convex edge on it (still trying to
perfect that, but it cuts pretty good now).
Cheers
