Add a state of the art OTF automatic to your rotation with the RECON-035 from Guardian Tactical. Guardian Tactical's patented OTF mechanism provides smooth, responsive opening action. The unique thumb slide design is separated from the aluminum handle by a steel plate and 3 ceramic balls that eliminate grinding and wear. An innovative locking mechanism sits off to the side of the blade channel so it doesn't drag against the blade when opening and closing. These features eliminate the friction on the blade and button that have always plagued OTF knives. Take your OTF game to the next level with the Guardian Tactical RECON-035.
