The German word Feder means "feather" or "quill", but came to be used of metal springs in the 17th century (i.e. at about the same time as the name of the sparring weapon and possibly influenced by it).
It is possible that the term Feder for the sparring sword arose in the late 16th century at first as a term of derision of the practice weapon used by the Federfechter (who were so called for unrelated reasons, because of a feather or quill used as their heraldic emblem) by their rivals, the Marx Brothers, who would tease the Federfechter as "fencing with quills" as opposed to with real weapons, or as scholars or academics supposedly better at "fighting with the quill" than at real fighting (reflecting the different professional backgrounds of the rival fencing guilds).
The tip of a Federschwert is spatulated and may have been covered with a leather sleeve to make thrusting safer, though no direct historical evidence exists of such use.
[3] Among some HEMA groups, it is believed that certain historical Federn had gradually thinning hilts, though this is not always applied to modern reconstructions of the weapons.
Pommel shapes also vary, between classic spheres, various polyhedrons, arming sword-style disks, or most commonly teardrops or eggs.
