The square faced design allows this hammer to be used against edges, borders, or into corners. The steel head is firmly secured onto a hickory shaft. Slackening the retaining bolt allows the faces to be rotated for the best striking orientation. The Wiha safety hammer is provided with a blue soft face, and a yellow medium hard face. Both are easily replaceable, non marring and designed to be used for many applications, such as window installation, furniture assembly, woodworking, joinery, light engineering, maintenance or paving.
