Sorry, didn't get this answered.

Consider me shot. My planer doesn't do picky finish work, it's 
here to remove material and get on with it. Yes, Delignit 
dulls steel blades, but so does rock maple. Neither has nicked 
a blade that I've seen, though I have hit buried nasties and 
nicked them. I have a back beveled blade set I use when I'm 
planing the Delignit, and maple, and a normally sharpened set 
for spruce. If I'm doing a bunch of maple or spruce, I'll put 
in the appropriate blade set. Otherwise, whichever is in there 
gets used as is. Even planing the Delignit with the normally 
sharpened set doesn't do them significant damage for what I'm 
doing.

Now I do have a significant edge fetish, and all my chisels 
and knives are kept quite sharp, but the planer is apparently 
outside that particular obsession for me.
