I love mine too. I carry it all the time. I will often pair it up with a .22 thick GameWarded from Busse, or my modded SS from them.
It is a great slicer, and has a really wicked sharp tip too. Great for piercing.
I have never had any issues with lock up. I believe I have the new version, but won't worry about it until I have an issue. I am not going to disassemble it just to check (some one said you could tell by looking though the holes tapped for the pocket clip).
I have a Recon1 I used to EDC a lot, but now it is usually a combo of the PB and a Busse.
Some one also said, if you broke the lanyard, you could not disengage the lock. (whom ever said that must have really weak fingers, because, when I read it or heard it, I went and tried it. No problem).
The action will get much softer. It is actually fast to deploy if you wanted to. I don't really flick mine (the soft handle metal will deform a bit if you flick it too hard or what not. Hardened spine meeting softer handle metal will eventually dent).
Thanks for posting that pocket/one handed close technique. I am going to give that a try, as well as the thumb push.
Again, I think it is a highly under rated knife. I find mine comfortable to use in whittling etc. The very thin overall cross section means it pocket carries very very well. Nice and flat.
Here are some comparison pics.
Closed
In hand. (it looks small in the hand, but it is actually a good sized folder. 4 inch blade iirc)
couple other knives for size comparison in hand.
Black Rhino
Modded SS from Busse.
Recon 1 old zytel handled Tanto I have had for 10 years.
Here is a spine shot for thickness
I am honestly thinking about buying one or two more for each vehicle. I would recommend this as a Boy Scout knife as well (as long as you really spent some good time educating them on the lock, and advising not to let anyone else close it until trained on it).
