Awlpike (Vlandian Peasant)
Metal Pitchfork but actually good (Vlandian Peasant)
Billhook (the OP one) (Vlandian Peasant)
Pugio (Imperial Recruit)
Flyssa (Tribal Warrior. He technically still has this, but all Perk 1 perks replace it)
Cavalry Menavlion (Courser. I think the Palatine Guard also had this)
Vlandian Bastard Sword (Vlandian Sergeant, Imperial Legionary)
Battanian Bastard Sword (Oathsworn)
Heavy Falx (Fiann)
Vlandian Throwing Axe (Voulgier)
Southern Throwing Axe (Guard)
Southern Pike (Skirmisher, Guard)
Should we also count weapons that are still in the game, but have been moved to other classes?
