One knife to rule them all! Our retractable hobby cutter is the perfect combination of utility and safety. The retractable blade is contained in a metal-framed skeleton, with a plastic housing for durability, and the flat shape of the handle guarantees the knife won't roll off your work surface and land in places you wish it wouldn't! Great for cutting sprue, plastic, resin and light metals. 1 easy-to-replace blade included - additional blades available in x5 packs!
