*Swiss, c.1958–1983, SIG Stgw.57 (Bajonett Mod. 1957) Bayonet & Scabbard, Victorinox - Waffenfabrik Bern, for Sturmgewehr 57*

Swiss Model 1957 knife bayonet for use with the 7.5×55 mm Sturmgewehr 57 (Stgw.57) service rifle. The bayonet features a single-edged spear-point blade with a pronounced central ridge and shallow fullers, bright finished throughout. It is fitted with the correct ribbed black synthetic grip, steel crossguard with muzzle ring, and mortised pommel incorporating the Swiss push-button locking mechanism.

The blade ricasso is serial-numbered V / 304177, identifying Victorinox as the blade manufacturer, and bears the circular W+F acceptance mark of Waffenfabrik Bern. The crossguard is stamped KV146, a standard Swiss inspection and control marking associated with Stgw.57 bayonet production. The grip shows the oval mould mark (commonly described as “M” or “W”), consistent with period-correct Swiss manufacture.

The bayonet is housed in its correct black composite scabbard (often misdescribed as steel), with steel throat and chape. The reverse carries a circular B over 5133 inspection/batch mark, while the throat is stamped P, indicating manufacture by Paillard AG, a known Swiss military contractor for bayonet scabbard components.

Approx. Measurements – Blade length: 23.5 cm. Overall length: 36.5 cm.

Historical Note:
The Bajonett Mod. 1957 was adopted alongside the Sturmgewehr 57, Switzerland’s standard service rifle from 1958 until the introduction of the SG 550 series in the late 1980s. Although often loosely described as an “assault rifle,” the Stgw.57 is more accurately classified as a precision battle rifle, reflecting Swiss doctrine emphasising accuracy, durability, and exceptionally high manufacturing standards.

In keeping with Swiss procurement policy, production of military blades was deliberately divided between multiple domestic manufacturers to prevent monopolisation and ensure industrial resilience. Bayonets for the Stgw.57 were produced by Victorinox and Wenger, with final inspection and acceptance carried out by Waffenfabrik Bern. Although Victorinox acquired Wenger in 2005, both firms remain historically distinct within Swiss military collecting.

The Mod. 1957 bayonet remained in Swiss service for several decades and is regarded as one of the finest Cold War-era bayonets, combining robust field practicality with the precision machining characteristic of Swiss arms production.

*Condition*
Blade remains bright with light service wear and fine handling marks consistent with issue. All markings are crisp and legible. Grip is sound with expected age-related surface wear. Locking mechanism functions correctly. Scabbard retains its original black finish with scuffs, scratches, and edge wear from service use; metal fittings show light oxidation. Overall a complete, correct, and well-preserved example. Please see photographs as part of the condition report.
