These unique, spring-powered tools are safe to use while also delivering extreme force and precision while marking, cutting, punching, starting, and/or setting, without the need for a traditional hammer. Ideal for use on wood or metal surfaces, these tools deliver up to 3,500 lbs. of striking force. Simply place the tool directly on the work surface, pull back the spring, and release – gaining extreme precision and accuracy while avoiding mishits and glancing blows.
