Were you able to handle an NMFBM at the show for comparison, or is that impression based on your memory? No offense intended, just trying to gather data.
I think it would be hard to predict the feel of the LBNMSHBM compared to other blades based only on what we have been told. The LB treatment affords Jerry the ability to fine tune the balance of a knife, whether he is trying for blade heavy, neutral, or handle heavy.
The NMFBM is a dedicated chopper, but I wonder if Jerry calibrated the feel of the LBNMSHBM to be more neutral, as more of a big, all-purpose knife?
Just to add, the NMFBM comes in .25, .275 and some in .30 so that would play a part when comparing these two blades. I have a NMFBM in .25 and had a .276 and the weight difference was huge, like day and night.
