Thank you Raull and BabyDuck. That is true, regarding the thickness, it would depend upon the appication. I imagine since this one is meant to cut as deep as possible that perhaps the thin blade is appropriate.

Any suggestions on how to give the blde a smoother edge? Should I spit the polys some more? Also is there anything wrong with using both quads and triagles on the same mesh? Should I go with one or the other?
