If a knife is advertised as being a virtually indestructible sharpened prybar, then I think it's perfectly reasonable to see if the knife actually is a virtually indestructible sharpened prybar. Almost all the knives Noss tests are being advertised as virtually indestructible sharpened prybars, so I don't see a problem with him verifying or debunking a manufacturer's claim. That being said, I'd never buy a virtually indestructible sharpened prybar, (VISP?), because such knives have very limited uses. (Read: they're useless.)
