What is a Pike? - Achaea Online Help

18.10.3 What is a Pike?

A pike is at least two different things:

1) a long, spear-like weapon with an often-interesting and/or complex point at
the end. These were often used by infantry to deal with enemies on horseback.
The term is also applied to the entire class of such weapons and would then
include halberds, gisarmes, and other exotic names that boil down to the same
thing - a long shaft of wood with some sort of blade or point at the end.

2) a sort of fish.
