Bought a 3300 infidel from the factory store, grinds are good, tips even and centered, however my blade edge runs against the inside of the case opening when deploying. I don’t obsessively deploy and retract, it’s not wear, as soon as I noticed I put it up. There is inherent blade play in this design but this is extreme, sent it in to Benchmade and supposedly Corrected the issue. They said it was “A flaw and not misuse” Got it back still rubs but not as bad. I carried a 3350 For a decade without a single issue.
