The head, handle, and everything else of this product is made of brass. It has been stored for a long period, and there is a slight surface clouding characteristic of brass materials. - This is a double-faced hammer. One side of the striking surface is flat, and the other side is slightly curved (convex). - There are some impact marks on the striking surfaces as shown in the images (images 3 and 9). There are also some linear marks on the head due to polishing with a polishing cloth. If you are concerned about these, please refrain from purchasing. We hope that those who enjoy practical use, as well as those who have hobbies such as collecting, will consider this item. Size: Total length = approx. 205mm Head = 70 x 20 x 20mm Handle (grip) = 185mm Weight = approx. 400gr
