Product detailed description

Toughbuilt - retractable knife with automatic blade replacement

ToughBuilt Reload Utility Knife

This is a retractable utility knife featuring a range of innovative mechanisms that make your work fast and safe.

 ToughBuilt stands behind the quality of its tools so much that it offers a 2-year warranty on all its products and a 25-year limited lifetime warranty if the tool is registered athttps://toughbuilt.com/. 

This knife is primarily designed to provide a quick way to replace the cutting blade on the go, thanks to two "buttons" located on both sides of the knife.You control the blade using the sliding mechanism on the top of the knife. On the right side of the knife, you’ll find the “Blade Release” button, which allows you to remove the current blade.Once the blade is removed, simply slide the top slider backward and then forward to reload the knife with a new blade directly from the built-in magazine.By pressing the "Mag Eject" lever, you then have two options: insert another full magazine or reload the current one.
