CS39FK: Double Agent I - Karambit Blade Style
Cold Steel®

Cold Steel’s Double Agent™ neck knives possess a significant set of advantages worth noting. Designed by Zach Whitson, with either a Karambit or Clip Point blade style, they’re thin, flat, and super light (a little over 3 ounces including sheath). This makes them easy to conceal and very comfortable to wear. Their most audacious and notable feature, however, is their double ring handle design. Slip an index finger through the front ring nearest the blade and your pinky finger through the rear ring and close your fist to obtain a forward grip and vice versa for a reverse grip.

It doesn’t matter how hard you cut, chop, hack, hammer or thrust with the Double Agent™. Its twin rings will always prevent your hand from sliding forward on the razor sharp edge and will likewise resist the effects of centrifugal force or the efforts of an adversary to wrest the Double Agent™ from your grasp.

Cold Steel!
The knife came super sharp out of the box and the blade fits securely in the sheath. It’s a very lightweight and thin knife as well, so daily carry shouldn’t be a problem. Overall I’m very pleased with this product.

Pros: Sheath/Scabbard, Weight, None
Cons: Blade Sharpness, Blade Material, Overall Quality, Materials, Handle Material, Finish
After having spent several days looking at Karambits, I settled on this one based on many great reviews. The quality of this knife pales in comparison to the Spyderco, CRKT and OKCs I own. Given the reviews that I read, both on this site and full write ups on the web, I expected much more. What I received resembled an over priced cheap Chinese knock-off reminiscent of something you might find in a bargain martial art store. I promptly threw this knife into a drawer with no thoughts of ever seeing it again. If you want a knock around knife that you can abuse and you can get this one for about $20, go for it. As for me, I would never consider another Cold Steel - regardless of the reviews. This is in no way a review of KnifeCenter's service. That was fine and as expected and I would continue to do business with them.

Scary Blade
A bit bigger than I expected, but overall has a nice balance and feel in the hand. Comes sharp right out of the box
