Manufacturer: FOURSEVENS

Model: FS-PKL-AF



In stock(Usually Ships in 24-48 Hours)


The FourSevens PK Knight Flashlight is a handy everyday carry light that offers some serious brightness. Shorter and stouter than a BIC lighter it is small and lightweight enough to drop in your pocket, yet powerful enough for practical to tactical use everything in between.  Designed in collaboration with Paul Kim (PK), the Knight is easy to function with momentary or constant on and offers 2 standard and 5 hidden modes.  Reversible pocket clip allows carry with the bezel in the upward/downard position.  Powered by a single CR123A or RCR123A battery.  Brand  new directly from FourSevens.

Operation:The PK Knight can be easily operated by using the tail cap for momentary or constant on.  A Tact-O-Click of the tail cap will offer momentary on while a twist provides constant.  Click or twist the tail cap once for low or twice for high output.

For everyday functionality, the two-mode interface is standard with a low and high out put while the additional 5 modes can be reached by cycling through the low and high outputs three times within 1.5 seconds.
