Honshu is the only weapons line that consistently fuses traditional ideals with modern innovation. Their Senjutsu Fly Butterfly Knife is more than a prop for performing flipping tricks. It’s a highly capable knife that can be used for self-defense or any cutting task. It has a 4” razor-sharp, 7Cr17 stainless steel blade with a satin finish that will rotate around bead-blasted steel torx screws. The handles are 6061 aluminum with a black, anodized finish and they are held securely closed with a stainless steel latch.
