The one I received had a horribly shaped head - a ball point hammer would describe it better! Of course, I could give it a more comfortable shape, which the manufacturer should have done. If you don't want or don't want to grind up this crappy product to make it usable, DO NOT buy it. I could easily make it at home as I have everything I need to make it. I thought it would be quicker to buy and it was, but I feel like I paid for something that should never have left production IF qualityβ¦
