CJRB CUTLERYPocket Folding Knife Centros (J1905) Dual Thumb Studs EDC Knife AR-RPM9 Steel Blade and Carbon Fiber Handle for Work Outdoor Hinking Camping

I have several of these and they lock up tight, no side play or blade stop slack.I replaced the plastic cage bearings that come with the knife with the Skiff metal cage ceramic bearings shown below. The pivot barrel is the D shaped capture style so if you choose to disassemble to the knife use the pivot head bolt opposite the liner lock.Even if you don't want to replace the bearings there will still be a time when you want to disassemble and clean the knife. Good luck if you don't have a manual impact driver similar to the AKM Hand Manual Reversible Impact Driver listed on Amazon at www.amazon.com/AKM-Reversible-Extractor-12-Screwdriver-Disengage/dp/B0BXKG4S17 or something similar.The knife requires a T8 Torx bit to loosen the pivot head bolt. Unfortunately for me, I rounded the corners in the pivot bolt torx hole because there was really stiff thread locker holding the pivot bolt. I thought I was turning the pivot head but I was spinning the edges receiving the bit ... duh!I had to pound a T9 bit into the pivot bolt head then use an impact driver to finally crack the thread locker and extract the pivot bolt. I cleaned the threads inside the pivot barrel and on the pivot head bolt. I can now disassemble the knife. I tried using a heat gun on the bolt to no avail before moving to the impact driver ... geez, CJRB ... give a guy a break!Other than playing my part as Dick Dastardly in the case of the rounded T8 Torx bolt socket, I have been very pleased with the build quality of these knives for the price.CJRB needs to have a talk with the thread locker guy and get him some low strength thread locker like Loctite No. 222.Skiff BearingPhosphor Bronze Cage Bearing - Pivot: 6mm,Ceramic Bearings: 1/16 in (13 ball)

Got it Friday, sharp enough to cut Jesus. Looks great, feels great, smooth as glass to open. Flawless condition, really was expecting disaster due to distrust of Chinese products but, pleasantly surprised. Hey bob in arizona, they got these things called torx screws and this stuff called oil... adjust and get it right. My God you expect premium service at entry price. Go spend $600 on a benchmade like good little brand slave.

Good value. No S35VN stamp on the blade, but knife is sharp, blade is hard and it's been taking a beating in EDC use with no chipping. One hand opening has been my experience to date- with and without nitrile gloves.

"【EASY OPENING】Thanks to the design of the CJRB Centros Series dual thumb studs, it makes it easy to open the knife with either hand. This feature is particularly convenient for left-handed people." NOT!I have purchased a number of knives from CJRB including my EDC, and they all performed flawlessly. This one, a Christmas present, arrived undamaged and in the packing and it was impossible to flip open. It was just possible to open with two hands. Not what I purchased, more like a Case jack knife and unlike any of my other CRJBs.It's Amazon right? Just pack it up and send it back. I ordered a more expensive replacement (different model) CRJB which will just make it for Christmas. The knife arrived this morning, it was out of the box for 5 minutes and then repacked as new, and ready to be returned. This evening I effected the return and I am informed that I will now have to wait 30 days for a refund for a defective product. This is totally unacceptable. That alone is justification for not purchasing ANY product from Amazon that may be defective, well maybe an anvil might be ok.The knife was well made, nice carbon fiber scales, powder steel blade and light weight. BUT IT DIDN'T OPEN. I am amazed that CRJB can ship a flipper knife that doesn't flip?My replacement knife from CRJB will be the last piece of hardware I ever order from Amazon..Summary: CRJB is a great product but the combination of a defective item and Amazon's retaining ones funds after shipping a defective product is unacceptable. So much for customer-centric!Caveat Emptor!

The media could not be loaded. This knife is excellent. Great action, great ergo, nice aggressive look and it was super sharp right out the box. Solid lock up along with an excellent detent.

It took a little bit of oiling and adjusting on the screw out the box but after that it flicks open no problem with one hand.

Excellent knife from an excellent company. The fit and finish is phenomenal for such a low price. As always Cjrb gets it right.
