I have just bought my first Spyderco knife...I bougth the Police model with Stainless Steel scales....I was wandering will it loosen up with time...I had been carring a Gerber Applegate Covert that was really fast to open (I loosened the pivot screw)....but the Spyderco does not have a adjustable screw and it is really stiff...Is there a to loosen it or will it just loosen with time.
