I carried a 4" tanto blade hald serrated Voyager for a coupl eyears as my EDC for utility work and defense. I never had to use it defensively, but felt better a few times for having it. I still own the knife (gave away the fully serrated and plain blade versions of the same model). It has been replaced by a Chris Reeves Small Sebenza when in dress (work) clothes or a Microtech Socom Elite when in more casual dress. I like both these knives more, but they do cost a lot more. That said, I still carry the CS when I'm traveling because I'm scared of losing the other two to an overzealous airport security drone (it goes in the check bag till I get where I'm going)so I do still use it periodically. The AUS8 takes a good edge but doesn't hold it as well as the BG42 or 154CM my other EDCs use. This is partially the steel's fault and partially attributable to the Cold Steel's rather thin (but sharp!) edge.
Overall the CS Voyagers offer a lot of bang for the buck. There are certainly better knives, but for little money, I think the Cold Steel offerings deliver the goods better than something like a CRKT M16.
Gerber has an SL 3.25G for not much more money with G10 scales and an ATS-34 blade if you decide on the drop point blade design. The liner lock seems a little thin, but the lockup has been tight on the knives I have handled.
If you can live with a slightly smaller knife, I have seen Microtech Mini Socoms available for around $100.00 new. This gets you into a 154CM blade, a solid Aluminum frame and an overall better knife than the budget choices mentioned above. Blade on the Mini is around 3" (the Socom Elite is a 4" blade but would raise the price a lot).
Of course if you can see your way to $100.00 for the mini Socom, but need a bigger knife, for only a few dollars more you can look at an AlMar SERE 2000 at around $129.00. It all depends on how far you want to go and what your priorities are.
Enjoy whatever you end up with.
