Features Detail * Blade slider is located at the top of the knife, as opposed to on the sides, to maximize handle space and promote a more comfortable grip over long hours of usage. * The slider has an automatic blade lock function that prevents the blade from being pushed back into the knife when applying force (up to 8kg/17lbs). * Body of the knife is triangle shaped, designed to be ergonomic and easy to hold as well as for an ambidextrous grip. * String cutting notch opening is located at the bottom of the knife for thread cutting. * At the back of the knife is a detachable piece where you can open the knife to replace the blade, but the piece itself also acts as a blade snapper.
