Blade

When referring to Swiss Army Knives, the term 'Blade' can have different meanings.

The most obvious definition of a blade in terms of SAKs is a knife blade, that is, a sharp edged piece of metal suitable for cutting and slicing.

However, blade can have a different meaning, especially when describing a SAK. In this sense, a blade can refer to any of a large number of instruments that fold into the knife. These can range from a pliers, bottle cap opener, or even a regular blade.
