Bahco ERGO™ Round Shaped Handle for files of rectangular shape (round, square, three square, etc.). Developed according to the scientific ERGO™ process, to reduce muscle tension and the risk of injury. The hard polypropylene core, covered with a thermoplastic elastomer, provides a comfortable non-slip grip, and the handle’s smooth contours fit into the hand naturally. As a safety feature, the handle covers the tang and shoulder completely to prevent the hand from slipping off the handle onto the file blade.
