CJRB Feldspar(Large) Folding Knife, 3.53" AR-RPM9 Steel Blade, G10 Handle | Liner Lock, Reversible Deep Carry Clip, Lightweight EDC Knife for Daily Cutting Camping Hiking Outdoor, Green (J1912)

Couldn't be happier with the quality of the knife especially for the price. 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.

It is truly amazing the quality and price. Not the perfect knife, but we all know that does not exist. This knife is small. I can hide it in my palm. That is either good or bad. The pocket clip is nice and high and it sits low in my pocket. The action is really where it is at. It opens a tiny bit with effort but once started you can flip it out with the wrist, "chuck" it open with a finger push, or use the thumb stud (it assists well but is hard to use from the completely folded position-hard with the small size). This knife, which I selected the natural green G10 handle, is beautiful and well engineered. I gave the high review because the VALUE is here. I will use this knife at work. It came very sharp. I bought it for the price and it is so nice I want to keep it nice. Also though I want to ruin it so I treat myself to the one slightly larger. I own expensive Italian switchblades and almost every maker brand knifes. THIS I will carry.

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.

This is probably the best pocket knife for the money you can get. Yes you can spend a lot more and get a better knife. But it's value proposition is hard to beat. What to like; Smooth action, curved edges, and a nice finish texture. D2 steel has very good corrosion resistance, edge retention isn't as good as some other materials. But as a pocket knife this is an excellent choice. Comfortable in the hand, small in the pocket and keen factory edge. Although if you work the edge a bit you could improve on it a bit. But as I said edge retention of their steel is just average. If you don't want to spend the money on a much more expensive knife with a slight advantage in edge retention. This knife offers amazing value, excellent ergonomics and a good fit and finish. The negative, nothing really stands out. I suppose you could re-grease it and get a better open. You could do a better job on the edge. But over all their is nothing this knife really fails at. Possible improvements, I'd like to see a half cerated version. Id also like to see a version with an easy open nub on the spine when closed. The opening is smooth with the flip of a wrist and a flick of your thumb. But I do like the quick action knives.

This knife is amazing. Came super sharp fresh out the box. Great smooth action. Extremely durable. This has become my favorite EDC and I use it all the time and have had no complaints. I recommend this knife to anyone looking for a high quality EDC at a super affordable price

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!

I have purchase three of these knifes so far. The first was as gift to someone, that person lives the knife. . after receiving the knife, i was so impressed i bought one for myself. i somehow misplaced that knife and decided to buy another. because well it’s a great knife. great knife, holds an edge, top notch and quality craftsmanship excellent choice if you need a knife money well spent

This is an excellent budget knife. The liner lock is strong and the action is quite smooth. There was a little roughness in the action at the very end of opening, but a drop of oil seems to have smoothed that out. I love the soft feel of the G10 scales with a really nice rounded shape that fits great in the hand. The size and shape of the Feldspar is perfect for my large hands. Note: the AR-RPM9 steel has gotten into some controversy because it's a bit misleading. According to Dr. Larrin Thomas, a metallurgist who specializes in knife steel, this does not appear to be a "Particle Metallurgy" blade. But that doesn't make it a bad steel. He believes it's essentially a 9Cr18MoV steel made with a Spray Form technology. Meaning it's probably a bit better than standard forged 9Cr18MoV. For the price I think it's a good blade steel in general. This is my second Feldspar, so I do really like this design.
