My favorite for years has been the Kershaw Cryo 2. I had one that I killed by accidentally cutting into a 220v line;) And I replaced it with the same blade, my only complaint is the blade steel is 8CR13MOV, which isn't great but it does the job and it's easy enough to sharpen. It's around AUS8 quality and hardness in my experience but I prefer the 9CR13MOV to the 8 just a little more carbon and a little harder at the end of the day. But overall my favorite pocket knife for a long time now;)
You can find them on Ebay pretty easily at a decent price, but the 2 is bigger than the 1, so the 2 is by far the one I prefer. However I should also note it doesn't look too "tactical" so if you open it in public it doesn't quite scare people in the same manner as other tactical knives either. It's no fixed blade but it's pretty dang good;)
