Here is the Knives of Alaska 3-Way Sharpener.
Black plastic pocket sharpener has ultra-hard carbide inserts to bring blade cutting edge to the same 18 degree angle that Knives of Alaska uses on most of their blades. It features a 2 1/2" fold-out, double-sided diamond grit flat sharpener and a fold-out, 2" diamond grit spike for sharpening serrations.
Closed length of sharpener is 3 1/2" by 1 1/8" by 5/8". It only weighs about 1.4 ounces.
It is no fun working with a dull blade. Carry this sharpener with you whenever you head out. Made in America and available here at Knife Command.
