To be an excellent hobby knife, it needs to be razor-sharp, precise, comfortable, and refillable. The knife needs to cut various materials from cardboard to vinyl safely. Powerbuilt fulfills those exact needs with the ingenious Hobby Knife with Retractable Blade. It’s a hobby knife with a twist. Twist the knife body to expose the blade for cutting, then twist it again to retract the blade closed between uses and storage. It’s lightweight and comfortable, with a generous sized barrel and rubber grip sleeve for added comfort and control. When it’s time for a fresh blade, pop off the end cap to access two extra standard-sized hobby blades stored inside. The knife also features a built-in pocket clip, so it’s always within reach.
