A knife that could easily be hidden and no one would know that you have it on you. A self defense mechanism or a tool with many uses. Handy on hiking trips, hunting, car repairs or cutting anything at all. It could even be a serated edged knife for handy sawing action. It could serve with many components of a Swiss Army knife if you only fit it into the size and shape of a credit card. It could even have a magnifying glass or a night light in it. You could potentially miniturize anything and put it into this credit card shaped and sized card. With this handy do it all you can pull it out in seconds or have several on hand for different uses.
