Saw one at a pawn shop as I was doing other business, didn't get around to picking it up as it was in a show case. I don't want this to end as a "I wish I had of", or a "I wish I hadn't of". It was a decent price in my mind, but that doesn't mean much in the real world. If I get around to going back and looking at it, what should I look for. I know cracks in the handles etc, but what about the function? Should it have a strong snap, should the blade have a audible click going back into place, or just feel it lock in? Should the "button" be easy to move, should it have spring tension even when open? I just don't know what to check for to see if it is in good shape, or needing repairs. As far as looks, I could tell it had been carried, laid around, gotten dirty, as the handles had lost any shine, but didn't see any cracks or gouges on the side facing up... Thoughts???
