War scythe

A war scythe or military scythe is a form of polearm with a curving single-edged blade with the cutting edge on the concave side of the blade. Its blade bears a superficial resemblance to that of an agricultural scythe from which it is likely to have evolved, but the war scythe is otherwise unrelated to agricultural tools and is a purpose-built infantry melee weapon. The blade of a war scythe has regularly proportioned flats, a thickness comparable to that of a spear or sword blade, and slightly curves along its edge as it tapers to its point. This is different from farming scythes, which have very thin and irregularly curved blades, specialised for mowing grass and wheat only, unsuitable as blades for improvised spears or polearms. Compared to a fauchard (which is believed to have evolved from the war scythe), the blade of the war scythe has the cutting edge on the concave side like the agricultural tool whereas the fauchard has the edge along the convex side. As an infantry weapon, the military scythe had practical applications both in offensive actions against enemy infantry and as a defensive measure against enemy cavalry.
