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. You will notice also that
some are made of a plastic material, making them less likely to
be considered a weapon. Each of these tools was designed to
cut and is fully functional in that respect. Whether used to cut
paper, cardboard, or other material, these knives should be
treated as potentially dangerous weapons. Each knife is shown
with an accompanying scale for size reference and many
include an X-ray photograph to show how these weapons might
appear if placed in luggage and passed through a scanning
device.
