The ToughBuilt knife is an innovative quick-change tool skillfully crafted from professional materials for heavy use. The patented quick blade reloading mechanism is activated by a smooth push of a button, ejecting the used blade, and a click loads a new blade from the magazine. Inside, each magazine holds 5 blades of any type, and the lower chamber reservoir has room to store an additional 10 blades. A simple press of the reset button ejects the magazine from the tool, allowing you to change blade types quickly and easily. The tool is made of aluminum and zinc alloys that give it corrosion resistance. The durable, tenacious, non-slip, soft-touch rubber body protects the knife from bumps and drops and provides a more dexterous grip. Integrated finger guard helps you safely cut tough materials.
