"This double-edged sword was found in the River Witham near Lincoln. It is an extremely well preserved example of the type of sword which was common from about 1300.
When new this sword would have been a fine weapon, and probably owned by a wealthy individual or knight. It is likely that the blade was manufactured in Germany, which was the centre of blade manufacture in Europe at this time. The blade is made of steel, which combines a sharply honed edge with the flexibility not to shatter in use, and is inlaid with gold wire to form an inscription which is yet to be deciphered."

Apparently it wasn't unusual for swords to have inscriptions, but many are decipherable. The link below is a paper on the topic.
