I just bought a new Pro Turbulence Crossbones from Knifeart. I absolutely love the knife. However, it does take a lot of pressure to open it, whether using the flipper or even the thumbstubs. Is this because it is new and will loosen up? Or, can I do something to loosen it a little? It's actually pretty difficult to open. I had a Zero Tolerance that opened rather easily. I absolutely love everything about this knife, but it is rather difficult to open...and I like to think I'm a pretty strong dude, lol. Just curious if this is normal or not as it's my first IKBS. Thanks guys.
