Ka-Bar Knives, developed for US Military during WW II:
"... Marine Corps issued Ka-Bar fighting utility knife..."
"...Marines were taught to use their new knife primarily as a
slashing weapon in the initial phases of
hand-to-hand combat."
"... Besides use as a fighting knife, the Ka-Bar has proved useful as a
utility knife, for opening
cans, digging
trenches, and cutting wood, roots, wire, and cable..." *
Ka-Bar knives avail. for civilian purchase thru retailers are the
same as mil. issue IIUC .
The monster who stabbed & killed these four was armed w a knife capable of
opening cans.
Grrr.
