Being an avid outdoorsman as well as a soldier I would like to express my extreme satisfaction with my recent purchase of a custom knife by Oklahoma City knifemaker Dwaine Carrillo of Airkat Hunting Knives. I have used many different configurations of knives over the years and I believe this rig to be the best thought out and well made knife and sheath system I've ever used. Not only is the knife top quality with a killer sharpened upper swedge, but the leather sheath is a work of functional art for anyone who spends time in the woods. It has a built in ceramic sharpener, detachable military style lenstatic compass and removeable magnesium firestarter. I also like the multiple attaching points that are incorporated into the sheath. It will rig easily to backpack, belt or tactical vest. The HK rifle sling clip at the bottom allows for convenient attachment in the inverted carry position. I rubbed a generous amount of Obenaufs LP grease into the sheath and its working like a champ repelling water and other grit from field use. I've even jumped this knife attached to my tac vest. I highly suggest any outdoor enthusiast to check out Dwaine's knives on www.arizonacustomknives.com they are the only one's I know of besides TAD that carry Airkat knives. I have posted threads on other knives I've owned so this is in no way an advertisement for Dwaine but I'll tell you from first hand experience he's a hell of a nice, down to earth guy who loves to make knives and it shows in his work.
