Knives come in a variety of colors and shapes. We offer two different types of knives. One is called a Heart Attack knife that you hold in between your fingers and use it as a self defense option by hitting your assailant.

The second type of knife we offer is a pen knife. It looks and works just like a pen but when the end of the pen is pulled off, you expose a 2.13 inch blade you use to protect yourself. Pen knives are available in gold, black and silver colors.
