"In the wake of the September 11, 2001, airline hijackings the FIREARMS AND TOOLMARKS UNIT of the FBI LABORATORY has started a collection of small and easily concealed knives. This is the first installment of a continuing effort to collect and distribute information on knives that otherwise may be dismissed as non threatening items. Many of the knives in this collection were commercially purchased and typically can be bought for less than $20. Some of these knives are common items found in most homes and offices."
