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.

A Wicked Agent of Self Defense
You can always count on great quality knives from Cold Steel, and this knife shows just that. It’s got a wickedly sharp edge and can pierce and slash like a beast. The only con that i noticed was it would be hard to hold comfortably for those with smaller hands and the sheath is definitely a pain to use when you’re putting the knife back in. Also when you draw the knife from the sheath, initially you are not able to have your pointer finger in its hole because of how the sheath is made, and you have to reposition it into it after drawing the knife. (This only matters to those who care about the ability to quick draw) But overall, for the price, this slim karambit is great and is going to get the job done.

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.
