I mean I personally wouldn't do that because it would scratch the f

k out of the spine. If you want to whack it a few times against a soft piece of wood then I don't see an issue as long as you aren't stupid about it. Watch your fingers.
Personally I don't like locking knives anyway, for legal, social, and safety reasons.
Locking knives intimidate people who probably wouldn't bat an eye at a common easily recognizable and socially acceptable slipjoint like a SAK.
Locking knives are more restricted legally than slipjoints. Knife rules and laws vary so much from place to place that it's just better to default to a slipjoint.
Locking knives can give you a false sense of security which can be dangerous if and when the lock should fail.
FYI, Spyderco is well recognized and generally well respected around the world. Nobody is above criticism but it's probably not a good idea to go after the more well liked brands, especially on these forums. You'll get dogpiled. It's happened to me a bunch of times when criticizing Victorinox or Leatherman, both of which I actually like. It's just that some people simply can't handle criticism of their favorite brands. Personally I think that's unhealthy. If you like something then it's good to criticize it every once in a while to help make it better.
