Some Merovingian seaxes

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. The name comes from an Old English word for "knife".[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.[2]


Old English seax and Old Frisian sax are identical with Old Saxon and Old High German sahs, all from a Common Germanic *sahsą from a root *sah, *sag- "to cut" (also in saw, from a PIE root *sek-). Scramaseax or scramsax (lit. "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.[3]

The name of the roofer's tool, the zax, is a development from this word.[4]

Amongst the shape and construction of seaxes there is a great deal of variation. The most frequent characteristics are:

In the continental Germanic area, the following types are defined for seaxes between roughly 450 and 800 AD, in chronological order:[5]

The general trend, as one moves from the short to the broad seax, is that the blade becomes heavier, longer, broader and thicker. Long seaxes, which arrived at the end of the seventh century, were the longest of the seax. These were narrower and lighter than their predecessors. Initially, these weapons were found in combination with double-edged swords and were probably intended as side arm. 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. In England long seaxes appear later than on the continent and finds of long seaxes (as opposed to knives) remain very rare in comparison to finds of swords throughout the period.[6][7]

Another typical form of the seax is the so-called broken-back style seax. These seaxes have a sharp angled transition between the back section of the blade and the point, the latter generally forming 1/3 to 3/5 of the blade length, exactly like a large version of a modern clip-point blade. These seaxes exist both in long seax variety (edge and back parallel) and in smaller blades of various lengths (blade expanding first, then narrowing towards the tip after the kink). They occurred mostly in the United Kingdom and Ireland, with some examples in Germany around the eighth to eleventh century. Some examples have pattern welded blades, while others have inlays of silver, copper, brass, etc.
