There's a difference between a brand whose products support (even tangentially) a given lifestyle and who uses imagery to reinforce that, and a brand whose products suggest a given lifestyle regardless of what the product actually is. Ferrari can slap its logo on anything and charge a premium for it just because they're Ferrari, the image of the brand itself has subsumed the products. Porsche launched Porsche Design for the same reason. Browning has done a great job of it, and a Browning logo sticker on someone's car instantly suggests a particular lifestyle.
The only mainstream "knife brand" that's really ubiquitous enough to be a lifestyle brand is Victorinox, and it has been an actual lifestyle brand for a few decades now, after branching out into watches, luggage, etc.; the Victorinox shield has a connotation of utility, practicality, etc. (FWIW, I've heard the post-9/11 airport security rules killed off a huge chunk of their business, so the new product lines were developed to compensate and keep their space in airport duty free shops, so I don't think it was necessarily a conscious effort like Ferrari or Porsche). Most knife brands are so far off the general public's radar that nobody other than an enthusiast is going to draw any conclusions from a ZT or Spyderco t-shirt; the general public won't have any idea whose logos they are.
You might be overthinking it; S30V is still stainless, it's not like they're pushing an M4 Bailout for use in or near water. I'm going to the Bahamas next week and will be taking my Drift and an H1 Dragonfly, but I'll take the Bugout too and let everyone know how it holds up...
