The Celtic Long Sword was a large, straight-bladed double-edged sword. It was the Close-Range Weapon of the Celt.
Description
The Celtic Long Sword was around three feet in length, with a straight, double-edged iron blade. Greek historian Diodorus Siculus descriped the Celtic swords as being "as long as the javelins of other peoples." The hilt had a very small guard, a single-handed grip, and (most noticeably) two backward-curving quillons near the pommel.
Uses
The Celtic long sword was primarily a slashing weapon, as the rounded tip was ill-suited for thrusting and stabbing. The Celts were famous for they're iron working abilities, and some historians even think that the Celts iron should in fact be classfied as steel.
