This is a long-knife or sword bayonet manufactured beginning in 1892 and used to about 1913. They were manufactured by various French arsenals to fit the Model 1892 Mannlicher-Berthier Short Rifle. It replaced the French Model 1886 "Lebel" Bayonet. They are well made and can be easily identified by a third "fullered groove" in the forward rib - or back-edge, opposite the cutting edge - of the blade. Single-edged, quality blade; with black composition or wood grips. All-metal "blued" scabbard. There were two patterns of this model bayonet originally. The difference being the length of the muzzle-ring. The first pattern has the rear of the muzzle-ring flush with the grips; the second pattern has a muzzle-ring that extends backward - over the grips - ~1/8 of an inch. This is known as the French Model 1892 Second Pattern Mannlicher-Berthier Bayonet.
Composition grips modified to wooden 1914, quillion shortened 1915.
