By obscure names I meant stuff like 'bec de corbin', 'bohemian earspoon (lol)' or the tons and tons of name-suffixes that come with prongs and hooks on polearms. Those names start to sound very silly with all the material, quality, etc strings attached.
And for the sword renaming: 'long sword' is a very ambiguous term which could refer to all manner of large, double edged swords. Bastard sword (as in crossbred, not 'you bastard!') is a sword made for both one and twohanded use. Found it appropriate as the DF stock longsword is used onehanded by humans, and twohanded by dwarves. Also called hand and a half sword.
Similarly 'scimitar' is a word describing any outwardly curved arab sword. Decided to replace it with the east-european saber (which was in turn derived from curved turkish swords) to better fit in with the rest of the weapons. Again, I could go crazy and make dozens of curved onehanded swords from all over the world, but as far as DF is concerned they all function pretty much the same.
Arming sword is a single handed sword of medium length, standard weapon for earlier medieval knights. Varied in length quite a bit; from 'shortsword' kind of length to cavalry sword length. Orriginally replaced shortsword with 'short arming sword' and added a 'long arming sword' for dwarves to have a bit more substantial onehanded sword but later decided to cut down on longer names.
Anyhow, (tl;dr version) the idea was to make the weapon set more history based and less D&D based. Seemed to fit with this project so I threw it in here.
Edit: enity file done. Packaged it with the weapon file for convenience:
