CJRB Cutlery Ria Liner Lock Knife Carbon Fiber/G-10 (2.95" 12C27 Satin) J1917-CF

  • Satin blade made from Sandvik 12C27 stainless steel.
  • Thumb stud opener with a ball-bearing pivot.
  • Black G-10 and carbon fiber handle scales over steel liners.
  • Liner lock to prevent unintentional blade closure.
  • Deep-carry, tip-up pocket clip for secure carry.


CRJB Cutlery makes a mean EDC knife, and the Ria is a prime example of this. Good EDC knives feature an accessible design, reliable materials, and quality construction—all of which the Ria has. Something that's not as necessary, but appreciated nonetheless, is style—something else the Ria has. You'll find it lightweight and wieldy, fun and easy to open and close, and wicked-sharp out of the box. It includes a deep-carry pocket clip to make carry easy and subtle.

Like this vibe, but looking for something more premium? Make sure to look at Artisan Cutlery, CRJB's parent company.

Josh R. on Sep 21, 2020

Been wanting a Ria since they came out. Wanted the CF version but wasn't available when I first checked a while back. So happy I randomly checked again and saw that there were more in stock! This thing is 100% worth the hype. SUPER slim so it carries like a dream. Very slicy. Fit and finish is excellent. This has quickly become my favorite office knife. If you've been thinking about a Ria, just do it. A killer value.

Picked this up to compare it to the Micarta variant
Gerald L. on Oct 10, 2020

I was under the impression that this knife, like most other CJRB's was in D2. Upon learning that it was in 12C27, I wanted to compare it to the Micarta variant in AR-RPM9. For MY particular cut tests, it made 105 cuts through 3/8" twisted sisal rope before it would no longer slice through paper on that portion of the blade due to it snagging. This is with the blade being at a 17 degree polished edge from a Work Sharp. I had previously done the same cut test with the Micarta variant, and the AR-RPM9 blade made 320 cuts at the same 17 degree polished edge. If you like the carbon fiber look, and don't want contoured handles like the G10 and micarta variants, pick this thing up. Otherwise, I'd suggest paying the few bucks more for the Micarta version as the steel performs much better. I have big hands (usually XL or higher sized gloves) and this thing is still surprisingly comfortable. Full 4 finger grip in normal grip, and very comfortable in a pinch grip as well.

Extremely stiff at first
Tasha v. on Jun 24, 2021

Somewhere between 3-4 for me. It took me almost a week of constant deployment and a touch of oil to get this knife to the point I could single hand deploy, which was frustrating as I do not have a lot of hand strength. My other criticisms are it is many of the edges feel sharp when they could have been more rounded off, and there's no jimping at all. This makes it feel very harsh to me. But, it is a beautiful knife with the CF, and it slices well. And now that I can immediately deploy it is fun to fidget flip. It rides in the pocket, even in women's jeans (small pockets) well. Great price. Worth keeping in my collection, but it wouldn't be the first knife I recommend to people getting into knives or to women.

Very Poor Deployer
Doug K. on Oct 1, 2020

I love the knife, and own two of these. My only disappointment is that “as delivered” both of my knives were very difficult to one hand open. I have since gone in and bent the liner lock back to reduce the detent strength .... but that affects the liner lock, so not perfect. I’ve seen this knife easily deployed on U-Tube, but both mine were so tight I could not one hand them without tuning the detent... and even then, I have many thumb studs that have better angles to deploy without killing your thumbnail. Wish the thumb stud was better placed, or there was a flipper option of this knife.
