Thank you for viewing! I plan to list many custom tools in the future. The product details are as follows: Total weight: approximately 750g Head: SK11 Stainless Steel Carpenter's Hammer Handle: Stainless steel 16mm square bar End: TONE 17mm socket (steel) Total length: 250mm I will manufacture and ship the items based on the above specifications after receiving an order. Please allow some time for shipping! Twisting the handle increases grip and makes it easy to use and stylish! Fine scratches may occur during processing. Meat welding is performed using TIG welding, and the welded areas are also polished. The finish is done with blue bar buffing. [About Custom Orders] I make tools at the request of a friend who is a construction worker. Since I don't use them myself, I may not understand specialized terms. I would appreciate it if you could provide detailed information when ordering. I accept changes to size and materials, twisting, drilling holes in the handle end, and welding wrenches, so please contact me. Materials are not in stock, so the price may increase. You can also change the head to a specified one, so please contact me! I will provide an estimate.
