It's not appropriate for me to comment on the quality of MMHW (because I'm his internet dealer), but I would like to address this pesky hollow grind issue.
Hollow grinds can maintain a stronger, sharper edge than flat grinds. There has been some assertion that material is more prone to binding because in a flat grind the material slides up and through the bevels, but with hollow it will jam into the concave area. It seems fairly logical, but I've been trying to come to terms with why in my experience and many people I've spoken with, it doesn't seem true; or as true as many people believe.
I wonder if the reason is that the
initial friction created along the sides of flat grinds creates more initial drag, while on the hollow, the concave area doesn't contact the material the way flats do. Of course once the material passes through this "void" in the steel, contact is suddenly made at the rising area of the grind. This is where the binding issue comes up.
Is it possible that the superior "slicing" action (less drag) counter-weighs the "hot spots" at the apex of the grinds? Maybe, maybe I'm just confused.
My main issue is that, for most real world users, a bowie knife is not meant to be
justa chopper. You want an exclusive chopper? Use an ax. At least in my experience, people who use them are using them as a multi-use camp/outdoor knife. That means cutting up critters-turned-dinner, shaving kindling, etc.- various cutting jobs-on top of chopping wood. So it's possible that flat grinds will wedge and thus chop better, but many believe that an excellent cutting edge is equally important to a big blade. I know that I will only carry hollow grind bowies with me on hunting, camping and backpacking trips.
But that's just me...
