Surprised by the strength
Mike S.
I hate hollow grinds and liner/frame locks.

So bear with me, it surprised me by how well it feels. My fav knife and EDC is a Contego from Benchmade. I thought this would feel flimsy and cheap. The lock was loose once, by the second time I flicked it, it tightened up. I've had sloppier fixed blades. Not quite, but it was real solid. In all angles. No wiggles. None. Flat zero. Better than the Contego...

Bad: I dunno, the blade just won't take a good edge. I'm not an expert but I have been able to put a shaving edge on a knife since I was in middle school. I'm lazy so I use a guide and diamond hone now. I spent longer than I usually do with a 62 RH blade. Sigh. Might be DAU Error, but can't get a satisfactory edge. Still happy I bought it. I just want a razor edge.

Thing feels like a tank. I feel like I could chop and hack all day with this.

I was pleasantly surprised to see bearings when I took it apart! Around 22 or so each side. After cleaning and oiling it started opening much much nicer.

As others mentioned if your fingers are pressing the lock bar in, it is hard to flip. You can thumb the blade open as it is large enough. Or just pull it open.
One of the best knives i've owned

Great flipper, titanium is nice, excellent blade length for everyday carry. steel sharpens nicely and holds a pretty decent edge.

doesnt get much better for value on this one.
Try it yourself

Ok so all the reviews on this are way off. This is a quality knife. There's no lock stick and you don't need an over travel stop. The clip is sturdy enough to double as one. The ergos might not be Hinderer or Spyderco good but they're not horrible. Perfect centering, 40-50% on the lock up and great action. Over all a great blade for the money and really customizable. If you're going to go based off any one review, let it be this one. Try it for yourself.
Good materials, poor design
Sean L.
It's well priced for a knife with titanium scales and D2 steel, but the design is pretty subpar. The overall size is quite smaller in hand, and the handle is very blocky and is thicker near the pivot than the butt, making for very poor ergos. The deployment and lockup are good. The blade is simple and functional, but the new text that Ontario is putting on their new models is very ugly and detracts from visual appeal.

Lock up on mine is tight. Materials and design is top notch. However having Taiwan on the side of the blade in gold lettering, destroyed me.
Should have been a winner............

A good buy for the money, but I think the quality control folks were at a sushi bar when mine left the factory. Really good fit and finish, but several problems out of the box. The blade was very loose. Lots of blade play and the centering was terrible. I broke out the Torx set and went through the drill of blade centering 101. It took a while, but the centering is perfect with no blade play. This knife should never have left the factory in the condition I received it. It's a cool knife but needs better quality control.
Could be great..... could!

Got the prime yesterday, I was hoping this would be a solid knife, but it AINT! Will be going back Monday. Love the materials, blade shape but that's about it. Does not have good lock up blade play back to front, lock bar is center of blade 1 day from factory, just doesn't seem like this one will hold up to everyday hard use, too bad.
Just an ok one...

This knife came fast, good shipping from Blade HQ. Now... This flipper is not for a large hands person, small hands will fit it right or maybe medium. The bottom of the handle can hurt your palm even when you try to flip it open. The lock bar kinda snags when you try to close the blade, flipping is kinda not smooth. Maybe it's brand new and needs a while to be used for better flipping.

The pocket clip appears to be a thin and can bend easy as well. Overall this is just an ok knife with very good materials but I expected better ergonomics. The lock bar closes the blade at 50% already with no play. Anyway if you are a demanding knife guy/girl this knife may not be for you .

After I thought I would keep this knife, I was wrong, I noticed it is really hurting my palm every time I try to open it or handle it, now it's on the way back, returned, so sad so bad. Nice materials but ergonomics are horrible for large size hands ...
OKC prime flipper

I've been using this knife for a few weeks now...

Good - Titanium/bearings/sharp out the box/Lockbar insert / flips smooth with bearings

Bad - There's play in the blade (front to back) no side to side..
No over travel stopper so it's easy to over extend to unlock and what I mean is the frame lock seems to not have a strong enough lock up its very easy to unlock(not good) very scary when in heavy use.

Overall - For the price point it's ok I won't pay a penny more...I've stopped using it cause the knife is to skinny for me to EDC meaning (in width) not length - I have medium size hands and it's to skinny wish it was made wider feels like my hand with a tight grip still feels like it's not enough to hold the knife tight
Very Disappointed

I was one of the first knife addicts to order the Carter Prime and I was probably one of the first to send it back.

The Good: Price, Titanium. very smooth, functionality and blade geometry.

The Bad: Pocket clip, the box

The Ugly: The handle design and Lock bar

Overall impressions: First, I will start by saying this knife has alot of potential. It's clean, smooth and has great blade geometry. But that does not make up for it the flaws and defects, and for me, it was the handle design.

But I'll start with the box, it was beat up and a poor, cheat presentation. the pocket clip was too shallow for most of my pants.

Next to the design and functionality of the blade, the handle design is the most important aspect of a knife, because after all, you must be able to hold the knife for, what could be long periods of time and if the handle is not comfortable for whatever reason, it just creates a very unpleasant experience. Unfortunately, The Carter Prime has a very sharp hot spot on the butt of the handles that stabs the palm of the hand relentlessly. After about 5 minutes in hand, the discomfort was unbearable. I don't understand why the handles were designed with sharp points on the butt.

The lockbar also had issues, I can't readily identify the problem, but it seems to me that the lockbar was cut to thin which allowed it to flex with the slightest touch, so if you're opening the knife, your finger can't touch the lock bar at all, the slightest pressure will impede the blade from opening. I think this defect and the fact that the lock bar does not have an overtravel stop, caused my Carter Prime to develop lock rock, which was the primary reason I sent it back.

overall, it's a nice EDC, at an affordable price point, but the annoying design flaws just drove me crazy. The Carter Prime was not for me.
Absolutely badass!!

I am so impressed with this knife! It's a great looking design with high-grade materials and construction, and at this price point the value is almost unbelievable. Great ergos, snappy action, decent weight for the thickness, and very sharp out of the box. What more can I say? The only tiny con is the cheesy font OKC used on the blade; kinda looks like it came from an old mechanical label maker.
