Exceptional!
I've collected knives for over fifty years and CJRB keeps knocking it out of the park! The Frack has great fit, finish, design and action with a great factory edge. It is big enough to be formidable, yet thin and light enough to be versatile. I could do without the large choil, otherwise it's a neat perfect EDC knife with a high grade steel. It's a steel steal! There is nothing budget about this blade except for the price.

Great action! Nicely machined. Incredible value.
Owing this knife makes me wonder why I shelled out as much money as I did for my MT MSI RamLock. The action of this knife equals that of my MSI, Griptilian and Adamas knives.For me- the blade is best deployed by a button press and a wrist flick. It doesn't take any force at all to speak of.Closing the knife requires a button press and gravity. The blade easily falls into place.Lock up is SOLID. No blade wiggle in any direction.The button lock is well engineered. The surrounding scale is nicely milled out- so the button head is flush with the scale. No accidental openings! Also- when pressing the button lock down- I don't feel it grinding against the blade until the blade unlocks.Nicely done. Color me impressed!Also- the ONLY sharp edge is the blade edge. EVERYTHING is precisely milled and smoothly chamfered.I can't find ANYTHING to criticize about this knife at this price. If it had a properly heat treated Magnacut or even M390 blade- at 2x the price I'd say SHUT UP AND TAKE MY MONEY! But AFAIK the AR RPM9 is still a good knife steel- and I'm sure it will serve me well.BTW- BIG BLADE! Bigger than I thought it would be. Probably would serve well as a general purpose kitchen knife.This picture I took is this knife next to a genuine Microtech MSI RamLock knife.The MSI is more grippy- but this Frack is just a lot more comfortable to hold. I suspect the Frack is going to be in my EDC rotation more than the MSI.I really like this knife!

Shut Up and Take My Money
Where to start? This thing is absolutely sick. At $70, it's the most expensive knife I've purchased so far, but spending $10-$20 more than many fine knives gets you 100% more knife from my past experiences. I had been searching the market for a large (3.5"+) folding knife without a flipper tab that wasn't comical or super aggro-looking for a few weeks and wasn't having any luck. CJRB knives all looked like the exact design I wanted, but the largest I could find was 3.15" or smaller, so I was looking elsewhere. After searching fruitlessly for a few weeks, the Frack popped up out of nowhere and it immediately became apparent that it was The One for me!I got the stainless frag pattern variation, and cannot say enough good about it. Whether its the texture of the handle, its fit in my hand, the smoothness of the pivot, the light weight, the way it disappears into my pocket despite its size...etc etc you see where I'm going with this. It came out of the box razor sharp, and the AR-RPM9 steel has held the edge extremely well with minimal maintenance since. The pivot action didn't need much improvement, but its somehow gotten smoother since breaking in a bit. And the sound it makes when you flick it open is SO satisfying! It's not quite musical in tone, but compared to the flat click most knives at this price point with G10/Micarta handles make, it's music to my ears. After a month of owning it, I'm still over here marveling at the sound every time I pop it open.All the guys on YouTube like Neeves Knives, Metal Complex, etc, have only positive things to say about the Frack, yet I still think it's underrated. At this point, I believe the Frack will eventually join the pantheon of the Great EDC knives.

No bad
I like it. It’s a big boy button lock. It all works well but does feel a bit sloppy in my hand, could just be me and how my hand deals with it. Still a solid sword of a button lock in all steel.

Smoothest Action!
CJRB does it again with this buttery smooth knife! The action is so smooth that I find myself opening and closing my knife throughout the day because it is so oddly satisfying. I purchased the black grenade scales version and really love the look of the scales as well as the blade, very sleek design. For the price of this knife you will feel like you got a much higher priced knife.I think CJRB has a lifetime customer out of me!

So far awesome, wish 15$ cheaper
So far so good haven’t had it long so can’t speak to edge or clip durability butSharpness: yikes! First test with finger tip press was unimpressed I think because the edge is more oblique (compared to my kitchen knives) but took it out to trim new grape shoots and it was like an anime cut, I swiped at the shoot but the shoot didn’t move (wth right) then it tipped and fell (anime like when they sword a person and at first looks like nothing happened but then they body falls in half) any way so far so good.Opening mechanism: my first button to close and open but it’s smooth and seems quality, I am considering tightening the screw to see if I can get a slower more controlled actuation. With the button pushed it’s like speed skate bearings.I wish it was cheaper
