I did get a small operators manual with mine, it gives instructions on how to dissasemble and sharpen the blades etc.
I checked my blades after your comments, and it's funny, I have one of the three blades that is like a razor, another is pretty dull (can run my thumb down without worry) and the third is in between (semi sharp). Not sure of the reasoning on this. I'm assuming they should all be at the very sharp level when new? Did you find anything out from Wallenstein?
