Specially designed Japanese pliers for unscrewing tight screws with a damaged head or slot. The sharp-toothed grooves at the ends of the inner jaws allow you to grip and twist round-head and cylinder-head screws close to the flange. Also useful for blocked and corroded steel screws or screws with unusually shaped slots.
