This auction is for a vintage X-acto knife in its original box that appears to be unused. The knife is 5 inches in length, and in excellent unused condition. It comes with two extra blades that are stored in the compartment located in the back of the handle, and a screw in plug to keep them secure. The outer box is not perfect, but it is in very good condition, and it is very solid. The top of the box displays a picture of exactly what the knife looks like. The handle of this knife is plastic. Everything else is metal. I do not know the exact age of this knife.
