F frank k Joined May 8, 2001 Messages 2,548 Nov 11, 2002 #1 I noticed that the Rc hardness listed on the Spyderco site for these knives in VG-10 is... 58-59 for the Calypso Jr. L.W. 59-60 for the Moran, and 60-62 for the Navigator. What is the reason for the different hardness ranges? Thanks! -Frank
