Folding Knife Feldspar(J1912) AR-RPM9 Powder Steel Black PVD Blade Carbon fiber Handle Pocket Knife EDC Knife, Carbon Fiber Handle

Really impressed with this knife so far. The design and green color look great in person, and several people have already complimented it. The blade came pretty sharp out of the box and has handled everyday tasks easily. For the price, it feels like excellent value and more like a higher-end knife. The action doesn’t fling open as easily as some other folders, but that adds a sense of safety and control that makes it a solid first or entry-level EDC.

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.

I am a chronic loser of edc knives. I have bought this knife 3 times now, and trying harder to not lose this one. The reason I keep buying this, is because it is the best knife design I have found. It’s beautiful, sharp, and endlessly fun to practice opening, and as long as you don’t wash the D2 blade in the dish washer, you have a quality, easy enough to sharpen blade. It switches easily to left handed (which I am), has a beautiful deep pocket clip, and the blade will easily get to hair shaving sharp with routine stropping. For the price, you cannot beat the beauty, ability, and quality of this knife. I have no need for $50+ knives as long as this one is for sale. It’s capable, strong, and sharp as anything as long as you give it the TLC that D2 needs. In a nutshell: it’s the best purchase for your money

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.

Wow, much nicer than expected for the price. Super sharp, very well made and beautiful finish.
