This knife sounds fantastic. Moras are functional and a great value, but relatively flimsy compared to even a midrange knife (I had a Cold Steel Master Hunter for a while). Plus the Mora's steel (Sandvik something or other iirc) is very corrosion resistant but won't have the toughness or edge retention of the more exotic steels used in higher end knives.

I'm too broke for an MK3 right now, but I ordered an MK5 (Doug's tiny skeletonized neck knife that comes in an Altoids-like tin) last night, just as a nod to this thread. A lot of careful thought goes into these things.
