The Double Duty gets the hook off the blade, where I sure don't like it and what it does to blade strength and performance.  I take care to see that the cutting hook doesn't impede normal and other knife uses.  Thicker handle design prevents cutting hook from interfering with different gripping styles.
4 3/4" 01 carbon steel blade.  Overall length 9", weight 5 1/2 oz.
Scales shown: Black G10.  Shorter version shown with thick Desert Tan G10 scales.
