I see two issues here: thoughts on a product and thoughts on a company.
If you like Benchmade's knives and not SAK's or vice-versa, this ad doesn't matter in the slightest. If you wanted to buy a knife from "Neo-Nazi Knifeworks" (don't look for it, I made it up) based strictly on their making a far superior product, then do so: it's a free market.
On the other hand, you could buy an awful, 85-cents-to-produce knife from a company that devotes significant resources to feeding starving orphan kittens. Fine.
Obviously, these are silly extremes, but they're meant to prove a point: clearly some people value the product more than what we might call the "corporate personality" of the producer. Others may feel differently. My suspicion is that most consumers value both and that most companies cultivate both. Take, for example, Spyderco. Great product and great corporate personality. I feel the same way about SureFire, Zippo, et al.
I might even go so far as to say that, while regarding products people simply want the best value, in terms of corporate personality people try to match their own personalities, or at least personalities they admire in other people. Perhaps a consumer who is, himself, competative and even self-promoting, would find this Benchmade ad appealing.
(In the interests of full-disclosure, I've got, like, 15 Victorinox products and 1 Benchmade. I like them all just fine.)
