Chape has had various meanings in English, but the predominant one is a protective fitting at the bottom of a scabbard or sheath for a sword or dagger (10 in the diagram).[1] Historic blade weapons often had leather scabbards with metal fittings at either end, sometimes decorated.[2] These are generally either in some sort of U shape, protecting the edges only, or a pocket shape covering the sides of the scabbard as well. The reinforced end of a single-piece metal scabbard can also be called the chape.
The scabbard chape is not to be confused with the chappe, a French term - rain-guard in English - on the sword itself, a fitting at the top of the blade in late medieval weapons, just below the crossguard of the hilt. The chappe fitted outside the scabbard, presumably helping to hold the sword snugly and preventing rain coming in (4 in the diagram). This would typically have been of leather, though everything about these is uncertain as no original examples have survived, and they are mainly known from art.
