I make pocket knives so I'm familiar with the liner lock design. My lock is 3/4 the thickness of the liner and that is how you want it. The blade isn't going to close on you unless you are using it like a fixed blade knife. The liner wears over time so all you are doing is reducing the life of the lock by filing it down. So you can open packages, cut string, whittle wood, cut apples, etc. Despite the description saying it has a tactical handle that doesn't mean it's a tactical knife, Don't jam it full force, tip first, into wood, expect to do ninja or special ops knife fighting and you should be just fine. The lock up on my knives is tight. No blade wobble from left to right or up and down. The blade is centered when returned in the handle. It drops down with a decisive click and is held firmly in place. I have two of these and if you are complaining about this knife you either got a lemon or you are expecting way too much from a knife under $40. The bearings are fine that come with the knife. There are 10 bearings set in a plastic cage. You can get a phosphor bronze cage holding 12 ceramic bearings from SKIFF for the CJRB Feldspar. It might be worth it in the long run. D2 steel is a really good knife steel. When heat treated properly it has very good hardness (around 60RC) and decent edge retention. It is semi-stainless steel and resists rust but if you are in a humid climate you will need to keep an eye on the blade and oil it. Oh, this is a martensitic stainless steel which can be hardened through heat treatment. 434 stainless cannot be hardened so if this isn’t D2 it is a stainless steel which responds to hardening and 434 does not. Overall a surprising find. Review: Outstanding Everyday Carry Knife! - The CJRB Feldspar is hands down one of the best pocket knives I’ve ever owned. From the moment I took it out of the box, I could tell the build quality was exceptional. The blade is razor-sharp right out of the package, and the D2 steel holds an edge extremely well even after heavy use. The action is incredibly smooth, making it easy to open one-handed, and the liner lock engages securely every time. The handle design is comfortable, with just the right amount of grip, and the overall balance feels perfect in the hand. It’s compact enough to carry every day without feeling bulky, yet large enough to handle tougher tasks without issue. Whether for everyday carry or more demanding outdoor work, the Feldspar performs like a knife twice its price. For the price point, this knife is an absolute steal. Highly recommended for anyone looking for a reliable and well-crafted EDC knife! ## Features - 【PROPRIETARY AR-RPM9 STEEL】The Feldspar’s blade is constructed from our proprietary AR-RPM9 steel that perfectly blends edge retention, corrosion resistance, and ease of sharpening. This is the ideal option for an everyday carry knife that will stay strong through all of your adventures. - 【SHARP DURABLE BLADE】The Feldspar features a wide drop point blade that tapers to a fine tip. The high flat grind ensures that the edge stays thin and slicey while the spine is robust and durable. Thumb studs allow for quick and reliable action whenever the knife needs to be opened. - 【CARBON FIBER HANDLE】Carbon fiber is an excellent handle material option. Carbon fiber is temperature resistant, water resistant, non-reactive, non-conductive, and exceptionally tough under pressure. Meantime this version of the Feldspar features flat textured scales rather than the standard contoured ones which gives it a slimmer profile and more grip while wearing gloves. - 【ONE-HANDED OPERATION ＆ CLOSURE SMOOTHLY】Our caged bearings ensure that your Feldspar will snap open with authority with just a little pressure on the thumbstuds. Closing the knife is just as fluid, simply disengage the liner and the blade will smoothly fall shut into the handle, making this knife the perfect for true one-handed operation. - 【EASY TO CARRY】The CJRB Knife boast a true deep-carry clip that will entirely disappear into the pocket. This is perfect for keeping your knife securely on your person while still allowing it to be accessible. The black PVD coating keeps the knife even more comfortably discreet in the pocket. The large lanyard hole is perfect for 550 paracord or leather cordage. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08T61T7T6 | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #49,445 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #103 in Camping Folding Knives | | Blade Edge | Flat | | Blade Length | 3.53 inches | | Blade Material | AR-RPM9 Powder Steel | | Blade Shape | Drop Point | | Blade Type | Drop Point | | Brand | CJRB CUTLERY | | Brand Name | CJRB CUTLERY | | Color | Black/ Carbon Fiber Handle | | Customer Package Type | [SAFETY SHIPPING BOX] | | Customer Reviews | 4.6 out of 5 stars 3,346 Reviews | | Hand Orientation | Ambidextrous | | Handle Material | Carbon Fiber | | Included Components | Knife | | Item Length | 8.11 inches | | Item Shape | Folding | | Item Weight | 4.23 ounces | | Manufacturer | CJRB Cutlery | | Model Name | Feldspar J1912 | | Model Number | Feldspar J1912 | | Number of Items | 1 | | Power Source | Manual | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Utility | | Reusability | Reusable | | Size | 3.5" | | Special Feature | Foldable | | Special Features | Foldable | | Style | Modern | | Theme | Outdoor | | UPC | 850024418240 | | Unit Count | 1 Count | ## Product Details - **Age Range (Description):** Adult - **Blade Material:** AR-RPM9 Powder Steel - **Brand:** CJRB CUTLERY - **Color:** Black/ Carbon Fiber Handle - **Handle Material:** Carbon Fiber - **Included Components:** Knife - **Model Name:** Feldspar J1912 - **Recommended Uses For Product:** Utility - **Special Feature:** Foldable - **Style:** Modern ## Images ![CJRB Feldspar Pocket Knife, 3.53" AR-RPM9 Steel Blade, Carbon Fiber Handle - Image 1](https://m.media-amazon.com/images/I/61pwazleCwS.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: What is the blade made of ?** A: The blade is AR-RPM9 steel.It has high wear resistant with very good corrosion resistance. **Q: What is the handle made of ?** A: The knife is carbon fiber handle.Carbon fiber has great properties that cannot be replaced by a series of other materials, such as light weight, high strength and good corrosion. **Q: Can you take the clip off?** A: Yes you can.

Highly recommended for anyone looking for a reliable and well-crafted EDC knife! ### ⭐⭐⭐⭐ Great blades, Good knifes *by D***G on February 14, 2026* I've tried the small and large versions of this knife and while both are nice in their own ways I think the ideal size would have actually been somewhere in the middle which is typical of a design that's offered in two sizes - you usually get the extremes instead of a happy medium. I wear L to XL gloves and in my hands the small one is a little too small, my pinky struggles to stay on the scales in a hammer grip and if I try to choke up on the blade the edge bites into my index - and while the big one offers a full grip (and then some) it's a little hard to maintain good edge and tip control when doing EDC things like cutting tape on a package because it's such a long knife. The smaller satin finished one worked flawlessly straight out to box and I've had it for ~3 years at this point without issue. No rust, holds an edge forever and it's easy to touch up with ceramic when needed. It's been taken apart several times for cleaning and I think I even swapped ceramic bearings with brass cages into it last time - it's been a solid dependable little knife. The enclosed liners took some getting used to but I eventually decided I liked how the handle feels. The pocket clip I'm not the biggest fan of, kind of long for the size of the knife but it does the job. The larger black one I picked up recently and two things immediately jumped out at me - the action is not very smooth and the lock sticks slightly. I suspect both are due to the PVD coating, it looks like the detent ball on the liner lock needs some time to wear a groove into the PVD before the action smooths out? And as for the sticking lock, while they did remove the coating on the part of the blade the lock interacts with the liner itself is painted (PVD?) and that appears to be what's causing it to stick. This should wear off in time and fix the issue, hopefully? I would also mention that the liner lock tension on this one is very stiff, so much so I think I'll end up pulling it apart and de-tuning it a little - out of the box it's tough to press the liner aside even after it's unstuck. One last note, a quirk I noticed - the liner spacers and stop pin in this knife are bright silver despite the rest of the hardware being black which makes them look a little out of place - would have been nicer if they were all coated imo. I think of the two I prefer the small version, even if it's a bit dainty for me - it's size gives me really good control over the bade when doing basic EDC tasks and in the end that's what I carry a knife to do. The lager model is more clumsy in comparison, but to be fair I have used the little one a lot and this larger version is still new to me. I do like the flat sided carbon fiber scales more than the rounded G10 on the small one, and while the pocket clip is the same length on the larger knife it doesn't feel oddly long. I think in a less urban setting the large model would be better as I can actually choke up on the blade when fine control is needed for something like carving or processing wood. Ultimately they are both good if slightly flawed knives. I hate to say that they are 'good for the price' because in truth they are really nice knives, well built and should last for years if minimally maintained - they just happen to also be cheaper than something like the Civivi Elementum or QSP Penguin which are better known. ## Frequently Bought Together - CJRB CUTLERY Folding Knife Feldspar(J1912) AR-RPM9 Powder Steel Black PVD Blade Carbon fiber Handle Pocket Knife EDC Knife, Carbon Fiber Handle - CJRB CUTLERY Folding Knife Crag (J1904) AR-RPM9 Powder Steel Black PVD Blade Carbon Fiber Handle Pocket Knife EDC Knife --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/280659813-cjrb-feldspar-pocket-knife-3-53-ar-rpm9-steel-blade](https://www.desertcart.tn/products/280659813-cjrb-feldspar-pocket-knife-3-53-ar-rpm9-steel-blade) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-27*
