Recently bought another Endura. It does not have a screw to losen up the blade to make one hand opening faster. Is there a way to get the blade to open more smoothly? This is my third Spyderco. I have a Endura (older modle) with serrated blade that is in bad shape, A Catcherman,Bird Rescue, and two Ladybug Salts on order. Starting to feel like a Spydeho.Also need to know how does the Endura compare to the Para Military? Thinking of one of those to add to collection.
