A similar tool is known in British English as a "Stanley knife", after one of the first manufacturers to create this kind of implement.
Another style is one in which a handle, usually of plastic, contains a long, segmented blade which slides out from it. As the endmost edge becomes dull, it can be snapped off from the rest of the blade, exposing the next section which is sharp and ready for use. When all the individual segments are used, it is thrown away or a replacement blade is inserted.
Though such knives are not usually considered weapons, they were apparently used in the September 11, 2001 attacks against the United States. See Airport security repercussions due to the September 11, 2001 attacks for further discussion. They have also been used by minor criminals in muggings, and some schools ban their possession on school grounds.
