negative blade angle (tip drops down from the axis of the handle) + properly contoured/curved handles = a knife that is truly a pleasure to cut with.
some people like the flat handles and straight blade angles which are more prevalent on BM knives, and they're certainly not wrong.
however the human body is shaped certain ways, and works certain ways. handle spines that curve, and palm swells simply fit the average hand better than a straighter handle. blades that angle down greatly increase your body mechanics in average cutting chores.
the fact that most flagship spyderco models offer these features to great effect gives credence to their "designed in the dark" mindset. they weren't designed to look how knives are "supposed to look", or to look pretty. they were designed to simply work as well as they can. any aesthetic embellishments come in addition to the ergonomics.
I wouldn't call bm knives "bad"in hand. they just make more knives that seem to look how knives are traditionally supposed to look, and don't nearly have that factor of feeling like the handle was designed for MY hand.
this is being pretty general, as both companies break from this simplistic mold I have given them, as both have a ton of models and options.
but if you put me in a dark room with six of each companies' main sellers, and told me to pick six to leave with, I'd wager at least four or five would be spyderco.
I could absolutely do my cutting tasks with a straight bm, but I get more joy from that fit in hand of a spyderco military or native. others get their joy in different aspects of the knife, or even go against physics and feel the bm actually fits better
once again, nobody is wrong. as far as build quality and materials there is no winner here. both are top of the game. so as long as you find one that fits your needs it doesn't matter if it has a butterfly on the blade or a tick -err I mean a spider.
