The MPL-50 (small infantry spade 50) was adopted by the Russian military in the late 19th century (it was patented and issued to the Danish army in 1870). It's still being used as a combat weapon today.

Since at least 1987, the Soviet/Russian Spetsnaz have supposedly trained to use it as a throwing weapon, as well as for more conventional hand-to-hand combat.
For anyone wishing to use the MPL-50 as a weapon in T2k, one could use the stat block for a hatchet.
