Doc what’s the key difference between hangers, sabres, messers, and falchions? Blade type? Curvature?
This question comes up quite a bit, and I’m sure there are some folks out there who will want to argue some of the finer points of this rather quickly dashed-off response, but here goes:
Hanger: A somewhat informal and very broad category that generally refers to a type of short sabre, like a cutlass. The “hanger” designation originates (I believe) in Britain, referring to the cross-belt and frog system for wearing it, but hunting swords throughout Europe and the Americas are also often called hangers. Blade length and guard are variable. Picture below is a modern production hanger by Old Dominion Forge.
Sabre/Saber: A single-edged, one-handed weapon typically longer than a hanger, carried by cavalry soldiers and by officers of infantry and artillery. The British, I believe, define a sabre by its blade shape, while the French define by the hilt/guard shape. The example below is French (18th c.), but would meet both British and French definitions.
Messer: Messer in German just means “knife”. There are all kinds of different messers for all kinds of uses. These are also often one-handed (not always), and single-edged. The Lange messer, Grosse messer, and Kriegsmesser are the most common martial forms, and although blade styles can be quite variable, including shape and length, all are distinguished by a knife-style handle, rather than a sword-style handle (see chart below of the Elmslie messer/falchion typology). Example below from Tod’s Workshop.
Falchion: Like a messer, wide variety in terms of blade shape and length, but always single-edged. The distinguishing feature is the sword-style hilt assembly (again, see the Elmslie messer/falchion typology chart). Example below is 15th c. Italian.
Zoom in to the typology below and you can see how interchangeable falchions (F) and messers (M) can be – it really is the handle/hilt assemble that makes the difference here.
