sledge hammer (also known as a club or stoning hammer)

The item shown in the image is a sledge hammer (also known as a club or stoning hammer) with a fiberglass handle and a two-component, non-slip grip. The handle is characteristically black and orange. 

The hammer head is typically made of forged steel. This type of hammer is designed for heavy-duty tasks such as demolition work, breaking concrete or rocks, driving stakes, and other applications requiring maximum impact force. The fiberglass handle helps absorb shock and vibration during use, while the rubberized grip enhances control and safety.
