In heraldry, a type of charge or heraldic bearing with a V-shaped fold or specific geometric design; an uncommon heraldic term.
From French heraldic terminology, possibly related to 'falté' (folded). This is an extremely specialized term from medieval heraldry with roots in Old French heraldic vocabulary.
Heraldry preserved hundreds of obscure Old French words that disappeared from everyday speech—'faltche' is one, surviving only in dusty heraldic reference books because coats of arms are basically frozen in the language of 1400s France.
