Graz, a maker on YouTube, turned an old circular saw blade into this polished metal pizza cutter that is as elegant and refined as the Wu-Tang Clan that inspired it.
The video is worthy watching in full. Not only is it funny with sound effects and scripting like a comedy sketch, it is also highly educational. I was impressed with how much went into heating, cooling, and tempering the steel so that it became a vicious weapon against all pizzas that it encounters.
