The blade lock lever is stuck in the "unlock" or open position. Is there a way to fix this (without voiding the warranty or having to take it in for service? I just purchased this 2 days ago and nit hasn't even seen action yet. The blade lock system worked well for the 30 minutes i had it before the spring lever became stuck!Any help would be appreciated!
