CR4040: Joe Caswell 4040 Provoke
Serve. Protect. The Provoke knife draws on ancient karambit design but it’s hiding a futuristic secret. The first knife ever to feature Kinematic technology, it stays neatly tucked away in transit and comes to life when there’s trouble afoot. Optional Boltaron sheath and clip set available.

CRKT thinks of Designer Joe Caswell as somewhat of a mad scientist. When they got an eyeful of the sketches that were to become the Provoke — designed in Newbury Park, California — they knew he was destined to become one of the most innovative designers the knife world has ever seen. Modeled after a traditional karambit, the black titanium nitride hawkbill-style blade is forged of a premium D2 steel for high durability and excellent edge retention. 

The opening mechanism is pulling the folder into the future whether it’s ready or not. Thumb pressure on the upper crossbar sets the chain reaction in motion, causing the blade to lunge to action while you’ve got a firm grasp on the handle. It’s crafted of aircraft-grade 6061 aluminum for supreme toughness. In true Joe fashion, the pocket clip is also a world’s first—sitting almost completely flush with the handle and likewise activated with light thumb pressure.

The Provoke comes up strong when it’s called in for duty.

How Kinematic Works

Nudge the upper crossbar with your thumb—while the rest of your fingers firmly grasp the handle—and the blade lunges to life and locks into place. Shift the discrete lever at the base of the finger loop and the blade retreats into its closed position.

Cons: None
Solid, well made, well designed.
I intend to use this kerambit mainly for self-defense/hiking/camping. This is a very solid, well made and well designed product. The overall quality of this kerambit is very, very good. It came out razor sharp out of the box.The size of the kerambit is a bit large for me, but it does not impede my movement in any way. Good and firm grip. The overall construction is very solid. The opening mechanism needed a bit of "warming up", but after a few times opening and closing it, the kerambit worked smoothly.Personal opinion: The blade could be made to curve in a bit more to give maximum hook//grip/damage to the intended object/subject.Overall, this is a well made, well designed kerambit that has a lot of potential.

Fun Factor
I was looking at it for awhile and finally decided to go for it. To be quite honest, I purchased it mostly for the fun factor. It's an awesome karambit to have fun with opening and closing it (mostly opening). Several reviews claimed it was hard to open and/or close. Mine was flawless. It's smooth to open and easy to close. The only so so part is the clip. Great idea of the clip sitting flush but it's hard to clip onto jeans or other thicker materials.As for the $199 price tag? Not so much but then again, it's the first of the kind.....

CRKT Provoke
I love the design of this knife. It came sharp out of the box. It's fun to open and close and easy to open and close and I have small hands. I see they made a sheath for it now, I may pick one up because of the weight, when I wear loose shorts it hangs a bit. Overall, I give it an A+!
