I just got this 5.11 "Investigator" Friday and have carried it over the weekend.
SPECS
I'm actually planning a better review for the testing forum after a few weeks or so, but I will give you my initial impression.
The factory edge was good, shaved hair on my arm from the plain edge part, and the serrations are very well done. (I am assembling some different ropes and cords to test them on, so more later).
The ergonomics are great, sits in the hand very well, and all the edges of the G-10 scales are contoured with now sharp "hot spots".
Solid construction, full steel liners and a solid lock and ZERO blade play in any direction, bank vaults should lock this tight!
At first, the knife was a little stiff to open, but after being oiled and opened and closed several times, you can feel it getting smoother and opening easier as the parts "wear in". I can now "flick" the knife open, but it does take a sharp snap of the wrist to thumb it open. (I assume their liner lock models would be easier)
Overall, I really like this knife and could see myself buying other models in their line, I found out a Police Supply store about 10 miles from me is listed as a dealer for them, so I plan to go look at more model first hand.
Hope this helps, I plan on a better review with pictures soon.
