My friends and I are huge fans of the M16 series.
I recently purchased an M16Z tanto tip and am VERY satisfied with what I got for $53 shipped. 4 inches of halfway decent steel, a VERY solid locking mechanism (but don't act like its a fixed blade, solid construction, and the "snap-click" of a good blade deployment is quite audible. That last bit is very important.
Its also a good selling point that even closed, this knife can be used quite nicely as a yawara stick.
The purchase was not for a "utility" knife, it was for a knife that will puncture anything from a car tire to a bulletproof vest while comfortably fitting in my pocket for EDC. You'll probably want to change the position of the clip. If you're looking for a "utility blade" this probably isn't the knife for you. The "thumb stud" is NOT a thumb stud, its a finger flipper that turns into a guard when the blade is deployed. You'll need to practice opening/closing the knife one handed, but after a day or two of playing with it you'll be able to whip the bastard out faster than most folks can even see that you've taken something out of your pocket. Its not classified as an "assisted" opener, if legality is a concern for you.
I opted not to get a spear tip, serrations, or the "EMT" style of knife because like I said... this wasn't a "utility" purchase. I put a bit more of an edge on it once I took it out of the box, but the tip is razor sharp from the factory.
Very happy with my purchase, and would buy a CRKT karambit fixed blade if they offered one. But they don't.
