The M1891 Italian Bayonet was developed to accompany the Carcano M1891 bolt-action rifle, adopted by the Italian Army in the late 19th century. The bayonet features a straight, single-edged blade measuring approximately 300 mm (11.8 inches) in length, with a fullered design for strength and reduced weight. Its hilt includes wooden grip panels secured by rivets to a full tang, a steel crossguard with a muzzle ring, and a press-stud locking mechanism on the pommel. Compact and functional, the M1891 was designed for infantry use, balancing reach and utility in a lightweight form.

Production of the M1891 bayonet began in the early 1890s and continued through both World Wars, with variants produced in large quantities by state arsenals such as Torino, Terni, and Brescia, as well as private contractors. Several million bayonets were manufactured to equip Italian forces, with variations in markings, hilt construction, and blade finish depending on the production period and arsenal. Later models included simplified versions with different blade lengths and finishes, reflecting wartime production pressures and evolving combat requirements.

The M1891 bayonet saw extensive use during both World Wars and in Italy's various colonial campaigns. It became one of the most widely distributed Italian bayonets of the 20th century and remained in service in various forms into the post-war era. Although often overshadowed by other European bayonet designs, the M1891 gained notoriety for its sheer ubiquity and association with the Carcano rifle, which was used in several major historical events. Today, the M1891 bayonet is a staple in military collections and is appreciated for its robust construction and long service life.
