The action is smooth and one handed, the blade is razor sharp.  The blade is rock solid when in extended position, no wobble.  The pocket clip is rock solid, unlike other knives I have owned.  I literally shaved my leg with it, no razor burn!!!  Now I walk around with a bald spot on my leg.  I also own the big brother of this knife, the pentagon elite II, they are the best folding knives I've ever owned.  I would recommend them with enthusiasm.
