so I chipped my nmfbm...

I believe you can go preeeeety thin. But..... Go slow. Looks like its doing pretty well as is. Just my opinion.

Thinner cutting edges, to me, are reserved for smaller slicey blades designated for less hard use. BUT. I'll be thinning the edge of my fat NMFSH at the first couple inches in front of the handle, while thinning the edge at the sweet spot less, and at the tip none. Should make a great all rounder at that point.
 
Yah I planned to thin the main edge and keep belly and tip portion a bit more robust.

My 2nd nmfbm, i only going to get the wicked edge pro treatment, so how fine I can get that edge!

News to me. Could you post a link to the thread on this changed INFI composition, please?

The latest thread talking about that was this one http://www.bladeforums.com/forums/showthread.php/1303390-INFI-is-tough-steel?highlight=Nitrogen
"Yes, the chemical composition has changed, it now has no Cobalt, Nickel or Nitrogen in it. I remember the big talk being about Nitrogen in the 90's and no one could figure out how the steel had it. In fact I even had one of mine tested and the place that tested were dumbfounded about N. The old INFI was expensive and probably not worth the extra cost and removing a few elements and dropping Rc a few points kept the steel tough(maybe even tougher) and reduced costs. If you think about the cost and availability of a BM today vs a BM in 1999, the BM's of today are a bargain. The new stuff appears to be closer to Modified A8 per your chart."

"INFI(Busse) - The composition shown in the primary record was obtained by a lab in Germany and it contains Nitrogen, which was confirmed by Jerry Busse (the presence of nitrogen, not the whole composition), although Jerry didn't dispute the results either. However, there is another X-Ray SEM analysis of the INFI steel, performed by Darrel Lewis, working at Inobond, child company of the Bodycote. The result is different, andat the moment I have no idea which one is correct, or those were two different INFIs. Alternate composition:
Carbon C - 0.64
Silicon Si - 0.63
Chromium Cr - 8.12
Molybdenum Mo - 0.85
Vanadium - 0.33
As you can see this one has no Nitrogen."

Excellent choice brother --- I have the Wicked Edge System --- I'm going to put a crazy refined mirror polished edge on my NMFBM and then thin the shoulders some ---- then I'm gonna beat it like it stole something
