I see the other fellas spoke of the other piece (which I know nothing about) but I do have the CS Recon1 with the clip point. That was my first real knife. I can tell you this much, you can absolutely beat the snot out of it and you aren't going to damage it, let me rephrase that....if you use it as a prybar you're going to break it but you aren't going to see that blade move to a side or get loose on you. The Tri-Ad lock is unbelievably stout but there is a pretty good breaking in period for both the blade and the lock - just work with it and both will loosen up as they should with time.
But the AUS8A steel really is a good steel. Very easy to sharpen and it holds the edge relatively well, depending on how long you're going to be out maybe bring you a sharpener with you (overnight or 72 hrs.) It locks up like a vault. You mentioned for self defense? You pull that out of your pocket and when that blade slams shut if people are around you - they will be looking to see what that loud noise was, and I am not embellishing in saying that. It is somewhat menacing.
The blade is covered with something different this year I think - but it looks pretty badass but will more than likely chip off over time with regular use. What I did was go to AutoZone and picked up one of those little bottles of touch up paint..they even had the satin/glossy kind that was on the blade. I would touch it up with that and buff it with the drimmel to keep it looking sharp but I have seen where it looks real nice without the paint job so I've been thinking about stripping it. {?} But it's a good knife, it was for me, I've kind of moved on to different makers etc. I'm sure you can't go wrong with either. Good luck.:thumbup:
