Some people may refer to the xacto knife as a small utility knife but does not provide the same kind of rigid cutting that a true utility knife provides. In reality it is a short, sharp blade mounted on the end of a pen-like aluminum body and can be used for hobbies and crafts. X-acto knives are great for precision cutting. You can think of this tool like a scalpel for artists and craft makers. It can also be used for fine woodworking and office supplies.
If you were looking for something that can handle a little more rugged abuse, yet provide semi-precision cuts then consider purchasing the Olfa Cutter Knife. We also have a heavy duty utility knife that can cut through thick corrugated plastic and other thick media without precision.
