The Boker Plus Access Prying Tool is a handy multi-purpose tool that can be used in many situations. The Access Tool is 5 mm. thick and ⅝ in. long, so it’s extremely lightweight at 0.7 oz. The tool was designed by Jasper Voxnaes and works as a bottle opener, shackle opener, nail puller and carabineer. Best of all, it is suited to heavy-duty use thanks to its sturdy titanium construction. It can even be used as a glass breaker in case of emergency, such as escaping from a submerged car. Ribbing across the sides of the tool ensure that no matter the circumstances the Access Tool will not fall from the user’s hands. Anyone attempting to use this tool to break glass should be sure to follow safety precautions. Limited lifetime warranty.
