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.

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

Cons: None
Using every day
This knife is ten times better than expected. I have been using it for landscaping work for weeks now and it has been amazing. The edge, size, shape and grip is what makes me keep on using it day after day. So if I can depend on it for all it has cut for hours day after day then it will be ready for anything else as I keep it with me all the time. BTW, It sharpens back up hair shaving sharp when needed and it last a long time before needing an edge dressing. Will buy more.

Great knife
This blade is great. Light enough to be worn around the neck. I was worried about the handle but it is actually quite comfortable. Very sharp right out of the package. I will definitely buy more from cold steel and my friends all want one also. Great buy. The only thing that needs work is the sheath. It needs bigger eyelet holes.
