Built for heavy duty and precision jobs, the Sure Strike 40 oz. Blacksmith's Hammer is designed for striking cold chisels, brick chisels, punches, star drills, spikes and hardened nails. Use this hammer with safety googles and bystanders should do the same. With this tool you get a strong reliable hit. This hammer has a 12 in. jacketed and textured fiberglass handle that allows you to get a heavier blow even with a limited swing. It has a forged steel blue painted head that is hardened and tempered with a New England Style design that has two very different striking surfaces.
