The head and hook are made of stainless steel, making them highly resistant to rust and maintaining their beautiful condition for a long time. The brass in the head provides a good weight balance between the head and handle, allowing for solid hammering with minimal force. The handle is made of aluminum, preventing it from becoming too heavy.
