Messers

Messers are a variety of upscaled knives that function essentially as swords. The word Messer actually means "knife," and most of these "big knives" are called things like the Kriegsmesser (warknife) or Goßes Messer (big knife). Messers often have a "negal" ("nail") that potrudes from the side of the crossguard to protect the hand. They are cheaper than proper arming swords, but are generally of lower quality. Messers are eminently similar to Falchions, with the only reliable distinction being that a Falchion has a more conventional sword-grip, and a Messer's grip is more like that of a knife--two slats of wood attached on either side of the weapon's tang.
In the Tattered Realms, Messers are common weapons in the Kaselreich and in Krajina, and given their cheapness, they're probably in use everywhere.
