Seax

A seax (Old English pronunciation: [ˈsæɑks]; also sax, sæx, sex; invariant in plural, latinized sachsum) is a small sword, fighting knife or dagger typical of the Germanic peoples of the Migration Period and the Early Middle Ages, especially the Saxons.

[1] In heraldry, the seax is a charge consisting of a curved sword with a notched blade, appearing, for example, in the coats of arms of Essex and the former Middlesex.

"wounding-knife") is sometimes used for disambiguation, even though it is not attested in Old English, but taken from an occurrence of scramasaxi in Gregory of Tours' History of the Franks.

From the seventh century onwards, seaxes became the main edged weapon (next to a francisca), sometimes in combination with small side-knives.

[5] The rest of Europe (except for parts of Scandinavia) followed a similar development, although some types may not be very common depending on location.
