What kind of weapon is a falchion?

A falchion is a one-handed, single-edged sword of European origin, whose design is reminiscent of the Chinese dadao, and modern machete. Falchions are found in different forms from around the 13th century up to and including the 16th century. In some versions the falchion looks rather like the weapon-seax and later the sabre, and in other versions the form is irregular or like a machete with a crossguard.

The blade designs of falchions varied widely across the continent and through the ages. They almost always included a single edge with a slight curve on the blade towards the point on the end and most were also affixed with a quilloned crossguard for the hilt in the manner of the contemporary arming swords. Unlike the double-edged swords of Europe, few actual swords of this type have survived to the present day; fewer than a dozen specimens are currently known. A number of weapons superficially similar to the falchion existed in Western Europe, including the Messer, hanger and the backsword.
