The Groz Fiberglass Blacksmith Fiberglass Hammers (also known as Cross Pein Hammers) are designed for light metalworking shaping jobs by metalworkers, welders, contractors, tradesmen and serious DIY projects. The rugged steel heads are forged from special steel and induction-hardened 50-58 HRC for unmatched durability. The head has one side chiseled and one side beveled. 

The lightweight yet sturdy dual-injection molded fiberglass handle with a 25% wider neck provides ultimate overstrike protection. The handle comes with a polypropylene jacket and a non-slip TPR grip for vibration and shock absorption. The handle is secured to the head using epoxy adhesive which can withstand rough usage. 

These fiberglass hammers conform to BS 876 and ASME standards.
