This video has been removed by the user <| sep |> just sold it for 188 <| sep |> Those are some nicely manicured nails , though . Look at that sheen . <| sep |> It ' s more used for the twist lock than the waterproof properties in a server room . You don ' t want someone accidentally unplugging a whole rack . <| sep |> That ' s the thing though I already addressed this . The only way you will inhibit the hands ability to grasp an object is severing the tendons , severing an entire muscle group , or hitting an artery . Not only do most cuts fail to do this , they also will have little no pain response either so you can ' t rely on psychological response when the physical response fails . So if your chances of physically inhibiting them are relatively low , and your chances of mentally inhibiting them are relatively low , what advantage does a knife offer over a baton for stopping an attack when a baton can break bones without having to worry about angle of attack or aiming for tendons or muscle groups , and can interrupt the mental processes of an attacker writhing strikes to the head ? It offers a higher chance to physically inhibit them and mentally inhibit them .
