Just got a Spydie Calypso Jr. that I ordered as a gift for a friend at work. Folding action seems smooth but if you open it slowly (not flicking it open) the action feels, not gritty, but rough. I looked closely at the pivot area and I couldn't see any washers or even a gap that would indicate washers. I don't want to send it back if this is a non-issue so I'm asking, is this normal for this particular model? I own Benchmades and they all feel silky smooth when opening.
