What sets this product apart is that it is the first product I have ever returned. When I opened the box, most of the cutters and pilots were scattered inside. Someone put it in a paint shaker. Several cutters had chipped edges. I paid a lot of money for this set and I don't have to put up with it. I sent it back for a refund. I don't feel safe trying to replace it because I doubt a replacement would be any better. Do not buy this product. You will be disappointed.
