The knives in this series feature a traditional frame lock for safety and a powerful deep-bellied spear point blade. This series also features the dual Carson Flippers for quick and convenient blade deployment—and the flippers double as an effective blade guard in the open position, a true “dual hilt”—a rarity in folding knives.

Review: Another perfect blade from CRKT - This is a beautiful, perfect , very small knife from my favorite company. First and for most I am a real life human not a bot. I can never tell if a bot or a human is writing these so let’s be very clear about it right now. The knife is good. I love this company and iv been using these knives specifically the M16 -14DSFG and this is the smaller version of that knife. It’s durable, it’s sharp, it’s very very comfortable and ergonomic. I love a double locking feature becuase it insure the blade won’t close on your hand. It’s perfect for small tasks that a big knife is too much for. I definitely recommend if you need a tiny knife for tiny problems. (I’m leaving the typos so you know it’s real. )
Review: Excellent small EDC knife - Owned this knife for over 2 years and it deserves a good review. Upon receiving the knife, it was smaller than I expected, even after watching videos and looking at pictures of it. Handle feels like the width of 2 ballpoint pens laid together, so it's not for heavy use, but this makes it completely dissapear clipped in your pocket. Lightweight and deep carry clip make it easy to forget about. I got the tanto tip and serrations, which look cool, but if I had to do again I would do away with the serrations. I don't find much use for them and they just make it harder to sharpen. A lot of reviews mention the AutoLawks extra spring lock, and truthfully, unless you're a complete moron, this is simple and nothing to complain about. Very easy to get used to, even in your non dominant hand. In fact, when I use other knives without it, they feel unsecure. There is no spring assist with the flipper, something I'm used to with previous Kershaws. This knife requires a motion similar to aggressively flipping a light switch off. Stays as sharp as can be expected, nice size, looks good and works great, could not be happier with a $30 knife. Note: The first knife that was sent to me through desertcart was very stiff. With all the strength in my pointer finger, (and I don't have weak fingers..I got some buff fingers) I could not use the flipper to deploy the blade. Sent it to CRKT and their replacement has been working flawlessly since.

### ⭐⭐⭐⭐⭐ My favorite day-to-day knife
*by F***X on September 7, 2011*

I own more than 70 knives -- most are folders -- and this is the one I carry every day. It clips unobtrusively inside my waistband, so I don't have a knife rolling around in my front pocket, bashing my keys or clanging around with coins. It lays comfortably at an angle and doesn't poke me when I'm seated at my desk or in the car. It's a small, reliable, indispensible tool. It cuts all kinds of materials well (from rope -- nylon and hemp -- to zip ties, cardboard, packing tape, and rubber hose). I like the partially-serrated edge for the tough jobs. I have another CRKT M16 with the drop-point blade, but I prefer the tanto point because it's more substantial when piercing tougher materials (like leather). Mine was sharp out of the box, but I gave the edge a quick freshening and stropping as a matter of habit. Like any knife it does require sharpening every once in a great while, but an occasional quick deburring of the edge keeps it cutting smoothly and cleanly, and extends the interval between sharpening. I've found that the CRKT M16s I've owned are a little stiff when new; the blade lock/release is particularly notchy. But if you work the blade open and closed a dozen times or so the locking/relase action becomes very smooth. I've played with the tension of the blade retention screw, but honestly I didn't see any benefit -- the several I own were adjusted well from the factory. This isn't really a self-defense knife -- it would need to be about 20% larger, and IMHO that would make it too large for a 'daily carry' knife, especially around the office. But the blade is stout for a knife of this size; the blade lock is postive and firm, and the handle provides very good grip even when your hands are slippery. So in a self-defense situation, I'd much rather have this knife at hand than most other folders. Overall, a great day-to-day carry knife. And at this price, it's a steal. UPDATE July 2013: Yes, I still carry this CRKT every day; still just as sharp and as reliable as the first day I bought it. Haven't had any issues with the blade locking system. Use this knife regularly and the muscle memory will take over in short order; it really is a one-handed operation to open or close this little gem. Only difference over the last two years is that I've bought a total of four more -- one for the glovebox of each car and one in the nightstand. Simple, well made, reliable, and a good value -- what more could you want?
