Unique fibreglass strands and bonding resin make each handle incredibly strong, as well as weather, chemical and insect resistant, unlike many traditional wooden handles. Fibreglass handles are unaffected by sub-zero temperatures and do not conduct heat or cold Handles are resistant to UV deterioration, temperature shrinkage, humidity deformation and protect users from potentially painful splinters The special fibreglass handle design allows the sledgehammer to deliver more power, while significantly reducing user vibration shock which is extremely fatiguing The Head and fibreglass handle are chemically and mechanically bonded for maximum strength and durability Made in the USA.
