All I can say about Busse is that the toughness turns me on because anything I could accidently do to it, it will most likely survive. I did chop into a concrete paver stone just to test the theory of Busse toughness, my TGLB held up really well, much better than my $40 Condor Kumunga in 1075 when I chopped into a bird and some deer legs.
Busse's style also appeals to me, they seem to have quite a few knives that really just catch my eye.
As far as fit and finish, they are simply the best knives I have ever held, and I have yet to find any ergonomic issues on the Busse and Kin I own or have used.
Another thing with Busse is that I have no doubts that I can use the hell out of them and still they will have enough life left in them for my children and thier children.
As far as cutting ability, I regularly use my TGLB in the kitchen and my Rodent Solution can skin a whole deer and not need to be sharpened afterwards, not a factory edge, but the Work Sharp makes quick work of giving a sweet 40 degree inclusive convexed edge, so they can cut super well if one is inclined to reprofile the edge.
