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.

  • Blade: 3"
  • Overall: 7 7/8"
  • Thick: 2.3mm
  • Weight: 2.5 oz.
  • Steel: Japanese AUS 8A Stainless

Great little knife
Love this blade. A little larger than many neck knives but the design as in most kerambits is very good. the dual finger holes allow for some real security to avoid a blade being used against you. Remember this is a defense knife. The holes also allow for devastating empty hand types of techniques with the blade. This in turn requires less blade skill to be effective. On the down side you do know you are carrying it as its length can be a problem at times. It is not an overly long weapon though. It would be great to have a sheath that can dual as an horizontal belt carry for front carry on a belt. If Cold Steel added that without the price going up too much Id buy a bunch.

Love it
I use this as a neck knife. It is large but comfortable. It came very sharp, fits well in my hand, and with practice I can now draw it from its sheath with the blade and either the up or down position. I highly recommend this knife.
