Del Tin reproductions of 17th century infantry swords from historical examples. I feel like a lot of Tumblr has this impression of unilineal sword development from arming sword to longsword to thin-bladed rapier (altogether missing that military rapiers up through the 18th century tended to maintain robust cut and thrust blades). A lot of military rapiers were cavalry weapons, with long cutting-capable blades for use on horseback. These are designed for an infantry crush in pike formations.
