Available Features and Options

One Handed Opening

Has a thumb stud, blade hole or other feature to facilitate one-hand use. Some models are one-hand opening and one-hand closing as well.

420HC Steel

This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process and you have a very user-friendly combination of superior corrosion resistance with excellent strength for wear resistance and durability. You also have a blade that is easy to resharpen. For best performance we harden to a Rockwell hardness of Rc 58.

Drop Point

This blade is full bellied with a strong, thick point for heavier tasks. It can also be used as a general work knife. The top of the blade drops down toward the tip, which minimizes accidental puncturing while skinning. The drop point blade is strong and very versatile.

I've had my Apex for a week.

It's been more than a week since I got my Carbon Fiber Buck Apex. The Apex is a ultralight, minimalistic EDC frame lock folder. Here are the specs: Weight: 1.7 oz. Blade: 2.62" drop point Blade material: 420HC with a black titanium coating Frame material: Buck says it is titanium but it attracts a magnet the same as the blade, which it would not if it were titanium. (I am guessing it is some flavor of ferritic stainless steel with the same titanium coating as the blade.) Scale Material: Solid Carbon Fiber Lock: Frame E lock First impressions: It is incredibly light, but very solid. Deployment is smooth and easily opened one handed thanks to an elongated hole in the blade. It was initially stiff, not flickable. The frame lock is what Buck describes as an E-Lock. The lock bar, instead of being on the edge of the frame as it is with most frame locks, is cut interior to the frame leaving the edge solid. This is a clever design for a knife where that edge is a primary gripping surface. Lockup is solid and leaves no play in the blade. The kerf cutting out the lock bar is incredible thin; making me suspect it was laser cut. The blade centering is spot on. The Carbon Fiber scale is reduced almost to a blade cover but still provides a solid anchor for the pivot. The pivot screws on both the frame and scale sides are backed by large washers. On the carbon fiber side these distribute the load and on the frame side, the washer also limits the lock bar's travel. I was pleasantly surprised that the Apex provided a crowded but usable four finger grip for my medium to large hands. The gimping on the top of the blade nicely anchored my thumb. All in all, a very comfortable, solid grip. This brings us to carry options. There are three. There is a thin pocket clip. There is also a built-in carabineer. (The carabineer also serves as a bottle opener.) And last, the pocket clip can be removed because the Apex is small enough to just drop into your pocket jack knife style. The blade came sharp out of the box and I have high expectations for the 420HC steel, as this is the same steel Buck has been using in its signature 110 knives since the '90s. Overall: Very solid and comfortable for a knife this size and weight Tuneup tweaks: I tend to tweak and fuss over every knife I get. The Apex didn't need much For comfort, I took off the sharp edges from the carbon fiber and frame. Then I lubed the pivot with gun oil. I added a lanyard around the rear spacer. While my Apex was on order, I emailed Buck and asked if there was room to do this. I didn’t get there response until after the lanyard had been on for three days. They said it couldn’t be done Finally, I stropped the blade a few times to tweak the already sharp edge and it was good to go. Current impressions: I have carried the Apex every day since I got it. I no longer think of it as a small knife, it is just "my knife". It surprisingly is the one that goes into my pocket everyday. Deployment has gotten easier but still isn't "flickable" Thoughts and recommendations Enlarge the carbon fiber to match frame contour for comfort. Right now the bottom of the grip is just one material thickness, about 0.090”. Extending the CF would increase that more than 3X to almost 0.300. this could be done everywhere except where you would need to access the lockbar to release it. In keeping with the minimalist design,the Apex is held together with just three Torx screws per side, the pivot, the stop pin and the spacer at the far end of the knife. That's good. Even better, all three screws are the same and use the same tool. This makes the knife easy to service. Unfortunately, that tool is a T6 which to my mind is too easy to strip. While I appreciate the desire to save weight, I'd redesign the Apex to accommodate T8 screws and make an already robust knife bulletproof. Personal preference here, I feel better with a bit of a finger stop. Bonus points if that coud work as a flipper. A real lanyard hole And my fantasy mod: a ball bearing pivot for kick a$$ deployment.

Great knife! Bad locking mechanism :(

I bought this knife months ago and love it but in a few months the locking mechanism doesn't lock any more, I'm afraid I might get cut.

Great EDC

I have owned 3 of these knives, and carry it every day. Light and slim enough that you don't notice its there, and easy to open one handed for frequent odd jobs (opening boxes, cutting cordage, etc.). I had the carbon fiber version for a couple of years, but lost it so bought another I liked it so much. The clip doubles as a bottle opener, which has been handy on occasion. Only gripe is that I had an issue with the pocket clip being too soft and it bent when it caught on something. I simply removed the clip and bent it back into position. It wasn't as tight as it was before, but it functioned fine.

One major & one minor issue

Purchased the carbon fiber edition of this knife at the BX on base as an everyday carry knife to replace my old Buck knife. Minor issue is that with an astonishing low amount of use the finish on the blade began to rub off. I've only had the knife maybe 3 weeks, used it twice and the finish is rubbed off. Not a big deal to me since i purchased it for functionality. The major issue is that the clip is made of a soft metal. It caught very slightly while clipped in my pants pocket and bent outward to an irreparable position. The force exerted was so slight that i couldn't believe it had even moved much less bent outward and held the broken positron. The clip is unusable and i am not happy with this product as a result. If the lifetime warranty doesn't cover this and isn't rectified in a timely manner then i don't see and Buck brand purchases in my future.

Superior Sleekness

I love the extreme low weight and slim profile. No thumb studs to snag or scratch your pinky when you reach into your front pocket and it's clipped there. Nice blade design, good steel holds an edge well. Carabiner clip can double as a bottle opener. This is the most comfortable EDC (Every Day Carry) pocket knife on the market. The unlocking lever is beautifully placed for sturdy handling when locked open, but ease of folding when the cutting is done. I am very impressed at all the design features that skeletonize the handle to lower the carrying weight: Cutaway handle design, holes, long slot cut into the blade for one-handed thumb opening. Didn’t care for the handle finish on my carbon fiber model. In pictures it looks like it’s textured to assist gripping, but in reality it’s a decal or print on a flat surface. There is one thing that is so poorly designed, I actually had to take off two stars: The clip. I can't emphasize enough how frustrating it is to try to clip this knife into your pocket while wearing denim jeans. It's too tight, and the bent-up portion of the tip is just too small to work on a stitched denim jeans pocket. Not sure how someone could design a pocket knife that won't work on your denim jeans pocket. I spent an hour with the pliers trying to improve the curve of the clip but finally gave up, as it just couldn't be bent into a functional position. I finally decided to just remove the clip entirely and carry the knife loose in my pocket. One other note – this knife is not for left-handers. The handle design blocks the thumb hole for lefties. This would be vastly improved by making this into an assisted-opening flipper design. Buck is really on the cutting edge with some of its design choices to make this the slimmest and lightest pocket knife on the market, but that clip needs to be shorter, wider, and curved to accommodate a denim pocket.
