Purchased directly from KC Tool through their website. If a surgeon needed a 10-ounce hammer, he would surely have it on hand. Simply beautiful and well made. In comparison, other hammers look really rough. Do you absolutely need this level of quality in a hammer? I personally probably don't, but FUCK, it puts a proud grin on my face when I see it on my desktop. This is the type of tool that will truly be passed down to your family for years to come.
