FEDERAL BUREAU OF INVESTIGATIONGUIDE TO CONCEALABLE WEAPONS2003

FORWARDIn the wake of the September 11, 2001, airline hijackings theFIREARMS AND TOOLMARKS UNIT of the FBI LABORATORYhas started a collection of small and easily concealed knives.This is the first installment of a continuing effort to collect anddistribute information on knives that otherwise may bedismissed as non threatening items. Many of the knives in thiscollection were commercially purchased and typically can bebought for less than 20. Some of these knives are commonitems found in most homes and offices. You will notice also thatsome are made of a plastic material, making them less likely tobe considered a weapon. Each of these tools was designed tocut and is fully functional in that respect. Whether used to cutpaper, cardboard, or other material, these knives should betreated as potentially dangerous weapons. Each knife is shownwith an accompanying scale for size reference and manyinclude an X-ray photograph to show how these weapons mightappear if placed in luggage and passed through a scanningdevice.
