SK5 Utility Auto-Knife
Infinity Knives is excited to introduce to you our newly engineered and designed OTF (Out-the-Front) utility razorblade knife with Carbon-fiber insert. This type of utility knife is characterized by its unique opening mechanism, where the blade deploys and retracts out of the front of the handle by activating the switch. It is a versatile and innovative cutting tool designed fora wide range of tasks.
This OTF utility knife is constructed out of 6061-T6 billet aluminum. All interior parts are 100% CNC machined for a precision fit and operation. The blades are interchangeable by simply pushing the spring loaded blade lock sideways on the designated arrow on the carrier to remove and install standard box utility blades. The clip is designed for right hand carry.
