I recently upgraded to a Shelix cutterhead on my DW735 planer. I have 2 sets of new DeWalt blades, and one set that has one edge that has had about 2 or 3 boards passed through. I am also including some used Infinity carbide blades, which I'm not sure how much life they have left in them and could probably benefit from some honing. $120 plus shipping for all of the blades.
