Its 52 HRC hardened alloy steel head delivers powerful strikes, while the vulcanized rubber grip reduces vibration and fatigue. The hi-visibility orange head enhances safety and easy identification on any job site. Engineered for heavy-duty demolition, metal forming, and stake driving, this hammer is a lifetime tool designed to outperform and outlast conventional models. ## Description Groz 34502 Indestructible Handle Sledge Hammer with 4-Pound Head and 16-Inch Handle features an indestructible handle made with six large spring steel bars, which run all the way through the handle to prevent breaking during overstrikes. The steel bars are locked with a steel plate to the top of the hammer head, ensuring the head will never get dislodged. The head is induction-case hardened to 52-56 HRC maximum power and extended life. The ergonomic, vulcanized rubber-grip handle absorbs impact and vibration, reducing user fatigue. Great for driving in stakes, heavy demolition work in construction like fracturing rock, stone and concrete, driving fence posts, iron / rebar work and bending or shaping metal. Also great for police fire and rescue applications as well as in railroad work. Sledge Hammers are used, abused & misused day-in & day-out - for heavy demolition work in construction environments, railroad, underground mining etc. These are rough use tools that take a lot of beating. No matter how much care you take, an incorrect strike of the hammer on the handle instead of the head cannot be avoided. Conventional Wooden Handle & Fiber-glass handles fall apart not just when overstriked, but after a few hundred strikes even when used with full care. The Groz INDESTRUCTIBLE hammer won't stop no matter what you do to it. Paying a little extra compared to conventional hammers for a lifetime of use works out to a fraction of the cost than what you would spend buying multiple units of conventional hammers for the same Job.
