The Hammer Club Copper 1.8kg Fiberglass Handle is a specialized tool designed for striking applications where a softer, non-marring impact is needed. 1.8kg refers to the weight of the hammerhead, which is 1.8 kilograms. This weight is ideal for heavy-duty tasks where a substantial force is needed, but without the risk of damage from a harder steel hammer. Copper Club: The copper head of the hammer is softer than steel, providing a non-marring impact. This makes it useful for delicate tasks where you want to avoid damaging surfaces, such as when working on metalworking, precision fitting, or striking tools that need to maintain their integrity. Fiberglass Handle: The fiberglass handle is known for its strength and shock absorption. It offers greater durability and resistance to breaking compared to traditional wooden handles, while also reducing the amount of vibration that is transferred to the user's hands. This hammer is commonly used in metalworking, automotive repair, construction, and other tasks that require precise, non-damaging impacts with a durable, shock-resistant handle. The copper head makes it a great choice for applications where the impact should not leave marks or damage the material being worked on.
