This series of sledge hammers from Estwing has a double-injected shaft reinforced with over 70% fibreglass, ensuring maximum strength and swing. They are ultra-robust, designed for durability, reliability and safety. The drop forged head is induction hardened. The thick handle has a rubber overlay below the striking head to provide overstrike protection. Additionally, the textured rubber grip helps reduce impact vibration and provides a comfortable and secure two-handed operation.
