In the 19th Century, each British infantry battalion had a ten-man squad of Pioneers, under the command of a corporal or sergeant. Their main tasks were to travel in advance of the main army, to clear the way and to undertake and supervise heavy construction work, often in enemy territory. The Pioneers were an early form of combat engineers.
Besides being a weapon, the saw-back sword was robust enough to replace the axes and hand saws usually carried by the Pioneers. The short, heavy blade could be used as both a saw and a machete and was of particular use when cutting brush to clear a field of fire and for clearing bivouac areas.
