The innovative Fox Radius is equipped with a novel opening mechanism, the patented Fingers Safe Opening System. The rotating mechanism is operated by a button attached within thumb's reach. By lightly pressing this button and then sliding, the blade opens and is simultaneously locked. Rotating backwards closes the blade again. The innovative pocket knife was designed by Denis Simonutti, a young knife maker from Italy. It is equipped with a black-coated, modified Wharncliffe blade made of M390 and an ergonomically curved titanium handle. With detachable clip (tip-up)
