Swiss Bayonet Model 1957

The Swiss Model 1957 bayonet (M1957) was specifically designed for the Sturmgewehr 57 (Stgw 57) assault rifle. This bayonet is known for typical Swiss precision and features a distinctive symmetrical, double-edged "dagger-style" blade.

Key specifications

• Blade length: Approximately 239 mm.
• Total length: Approximately 370 mm.
• Barrel ring: 22.2 mm diameter, fitting the muzzle brake of the Stgw 57.
• Material: High-grade chrome steel, usually chrome-plated to prevent corrosion.
• Handle: Black ribbed synthetic material (neoprene or composite).

Manufacturers and markings

Production was divided between two well-known Swiss companies. You can identify the maker by the stamp on the ricasso (the base of the blade):

• Victorinox: Early models are marked with "Victoria Schwyz" or "Victoria". Later versions have a simple "V" above the serial number.
• Wenger: Early models show the full name "Wenger"; later models use a "W".
• Control stamp: On the back, you often see the "F + W" in a circle, the stamp of Waffenfabrik Bern, which performed the final assembly and inspection.

Scabbard and accessories

• Scabbard: Made of black plastic with a steel mouthpiece. Often marked with an italic "P" from the manufacturer Paillard AG.
• Carrier (frosch): Used to attach the scabbard to the belt.
• Compatibility: Although made for the Stgw 57, the locking mechanism also fits the later SIG SG 550 (Stgw 90).
