Its also easily and conveniently carried in a pocket. * With a blade in the 180 degree position, a foldup can be used for spinning a fastener in or out. When opened to 90 degrees, it can be used like a screwdriver. * Care should be exercised when using a foldup with a small blade size. The very nature of the foldup design makes it possible to over-torque small blades.
