Scramaseaxes
Another relatively cheap weapon used during the sixth and seventh centuries was the single edged knife - the scramaseax. Scramaseax is a term covering a wide variety knives from small eating knives to large combat weapons. For the sake of simplicity, the term scramaseax shall only be used to describe the weapon in this section. The typical scramaseax of the Migration period, as found on the Continent, is about 8 - 14" (20 - 35 cm) long with an asymmetrical tang. Large scramaseaxes do not appear in England until the latter part of the Pagan period, with the earlier types generally having blades of about 6-10" (15-30cm) in length. The guard is generally insignificant, or even non-existent, but many of the early scramaseaxes had decorative pommels, often boat-shaped or lobed. By the ninth century very long scramaseaxes start to appear, more a single edged sword thab a knife. The blades of these scramaseaxes are between 22 - 32" (55 - 80cm) long and very heavy, capable of delivering a horrendous cutting blow. This type of scramaseax is probably the type referred to as a langseax (O.E. 'long-knife) in contemporary sources.
Two basic forms of scrameseax were in use in England. The Germanic type has almost parallel edges, with a sharply angled back. A single narrow fuller sometimes runs down one side, or rarely both sides, of the blade, just below the back. This type is not usually seen any earlier than the seventh century. The Merovingian type has a more curved form, and often has one or more fullers on both sides of the blade. This type first appears in England during the later fifth century, reaches a peak in the sixth century, and is gradually replaced by the Germanic type in the seventh and eighth centuries. Both types have blades of triangular section. Handles were usually of horn or wood.
Scramaseaxes were carried in a leather sheath at the warrior's thigh and the sheath was suspended from the belt by means of a series of small bronze loops. Some scramaseax scabbards appear to have been made of leather covered wooden laths, in a manner similar to sword scabbards. Many scramaseax scabbards have decorative chapes.
Scramseaxes are found in around 5% of the Anglo-Saxon burials that contain weapons.
