A falchion ([fɔːlʃən], from Old French fauchon, ultimately from Latin falx "Sickle") is a one-handed, single-edged sword of European origin, whose design is reminiscent of the Persian Scimitar and the Chinese dao. The weapon combined the weight and power of an axe with the versatility of a sword. Falchions are found in different forms from around the 11th century up to and including the sixteenth century. In some versions the falchion looks rather like the scramasax and later the sabre, and in some versions the form is irregular or (as is the case in the picture to the right) like a machete with a crossguard. While some propose that encounters with the Islamic shamshir inspired its creation, these "scimitars" of Persia were not developed until long after the falchion. More likely, it was developed from farmer's and butcher's knives or in the manner of the larger Messer. The shape concentrates more weight near the end, thus making it more effective for chopping strikes like an axe or cleaver.
