I just got a salt of questionable quality and when looking at the serrations closely I noticed that the tips of some of the serrations are rounded and not pointed. Only one or two are pointed sharply like on my D3. Is their a reason for this? Also this was the first serrated Spyderco that I ever recieved that was already sharpened on the back side of the blade. I also noticed that the serrations are spread further apart. I'm not too happy with this one, it also had tons of blade play when I got it and the lock sits to one side. I had to tap it on the Anvil to tighten the blade. What's the deal?
