Gerber knows from experience that what’s in your pocket says a lot about how you see things. The Gerber Contrast’s bold lines and sculpted shape are visually striking, but the real statement comes from how it feels in your hand. The combination of super light, deeply textured G-10 and steel in the body means it stays put no matter how wet the conditions get, with a deft balance point between ultra light and sturdy. Already popular as a rugged daily carry knife, dispatching small cutting tasks and utility work with ease, this evolution of the Contrast includes our advanced Assisted Opening 2.0 mechanism, for fast, one-handed deployment of the drop point blade—no need to stop what you’re doing to get your knife open and ready to use.


The Contrast’s looks set it apart, but every part has a role. Designed to perform when needed, and then sit comfortably at the ready when not, every curve of the knife is considered. The G-10 handle creates a super light body that’s impervious to rust and corrosion, resists temperature change, and offers positive grip, even when wet. Paired with stainless steel, the body is tough enough to withstand everything from light-duty shop work to heavy-duty outdoor tasks. The matte black finish on the handle and the blade gives the Contrast a low profile, tactical look that hides its utilitarian nature inside.


You shouldn’t have to think about your knife, except when you need it. At 3.3 ounces, the Contrast won’t weigh you down, and its 3-inch blade means it can work smoothly around big jobs. The Assisted Opening 2.0 mechanism delivers reliable, one-handed deployment, and the thumb Plunge Lock on the handle offers smooth release when closing, keeping your fingers away from the blade’s path.


A removable pocket clip lets you carry the Contrast easily in your pocket, or secure it to a bag for fast access. Thread the cordage of your choice through the lanyard hole for added security and quick location on the go.

I've owned this knife since 2013, it's by far my favorite knife. I've owned several other high end name brand knives that were far more expensive, including other Gerber knives. I have zero complaints about this piece, the assisted opening has always worked like new. The blade has always held a good edge, i do take a stone to it daily though just because i believe in regular maintenance on any tool. The thin profile handle makes it very comfortable to carry to the inside or outside of your pocket. I love the plunge lock setup, liner locks always put undo stress on the blade when closed, pushing the blade out of center with the handle. This knife has always had good balance and been straight as an arrow. I would recommend this knife to anyone, but everyone is different. Good luck in your search.

I have had this knife for years, I use it on a regular basis, it stays sharp pretty well, and has never needed tightening, It has always worked flawlessly. Great look and feel.

This is an update on my previous review of this knife. After getting use to it I must upgrade my rating to 4. I have gotten use to its nuances and it works very well for me. I have small hands. To open, I flip the thumb stud like flipping a coin with the tip of my thumb behind the stud and the blade fires out as good as an auto. If you have big meaty sausages for fingers it might not work so well. Trying to flip it with the thumb stud does not work that great. Blade takes a great edge, but they could have used a harder steel for better edge holding. The handles could be a little thicker as well. But all in all I like the knife very much. Would love to have an automatic version.

I did not read reveiws for the Contrast AO. This is my third Gerber and received it as a gift. First it is a Gerber and is a well made attractive knife. The hollow ground blade is a plus for me. Although I'm use to reaching for the liner to unlock the blade the plunge lock is nice and works well. As others stated it falls short with the spring assit opening. It does not work well at all. Lacks power and is difficult to get my thumb in position and grip the other side to hold when you push. Not thinning the handles might help with that. I would like to give better rating because it is a well made knife. Gerber dropped the ball on details.

I received mine as a gift, and have more experience with CRKT. I'm very disappointed with the "assist". It's very difficult to open, and after reading other reviews I don't think I will risk my tools on it. Other than that it seems pretty well made so far, but with that major flaw I have to say I probobly would be hesitant with purchasing another Gerber.

I have to agree with the person that gave it one star. Mine was really hard to open and I blistered my thumb like he did! I tried like survival instructor to adjust the pivot bolt and destroyed two bits from two expensive torx sets as well as rounding out the screws, they were just ridiculously tight. I own hundreds of knives so this was not my first rodeo adjusting tension. It was , however, the first time I damaged my screws and bits. I emailed Gerber about this and am awaiting their reply. I live in Canada so it will cost me almost as much as this knife is worth to send it back plus I will have to buy more torx kits to replace my bits. If this does not turn out favorably, this indeed will be my last gerber, and this is unfortunate as I own quite a few. This being said, had I know this, I probably would never have purchased this knife. In all honesty, this is the first knife that I could not recommend, and that's a shame because I love the look and feel of it.

Knife came sharp as all hell. Keeps the edge. The serated/straight blade is great for any task you may rub into. Nice weight and balance. The AO is is fine... the guy who gave 1 star probably got a one off bad unit and swore off Gerber... Let him. He's missin out on a good knife. Like the survival guy said... You keep you blade correct then your AO's gonna be fine. This thing opens smooth and fast. Plunge lock and thumb bolts are right where they should be. No reaching for the lock. If you're looking for something to keep in your pocket for utility or personal safety this piece will do.

This knife is terrible. The assisted opening DOES NOT WORK. Adjusting the primary bolt DOES NOT WORK, and why should the consumer have to alter the knife out of the package anyway? A big disappointment from Gerber.

I was very disappointed with the "Assist Opening 2.0". I have another Gerber with assist and it opens easier than this one.

I agree with Average above. Mine is not hard to open, but I certainly would not consider it "assisted " by any stretch. Nothing like my CRKT with Outburst.
This is still a nice smaller EDC knife

Bought one of these 2 yrs ago and use it daily!! Love every single thing about it!! Easy to open with the "assist opening" and feels great in the hand. I can't say enough about this knife. Best knife I've ever bought!!

This knife shaves like a razor out of the box. It is great looking and feels even better in the hand. The assisted opening works great. I can't wait to use it to clean deer and small game.

This knife opens great. But when it is locked it does feel impossable to open, but then again thats what the lock is for, when lock is diengaged the action is smooth and swift.

I think if you treat your blades right you won't have the AO issue occur. Also is it's too tight you can always adjust the primary bolt. Mine works without any adjustments. Fast and reliable.

The specimen I received was terrible! The assisted opening didn't work at all! In fact, it did the exact opposite and opposed the opening of the knife. It was so ridiculously hard to open that I got a large, painful blister on my thumb after 10 minutes of opening the knife because I had to push so hard on the thumb studs. I would definitely not recommend this knife and this could be the last time I buy from Gerber
