This was the standard knife bayonet issued and used by the Germans ins WWI and WWII. Manufacture originally began in 1898 - the new era of the 1898 German Mauser - and continued in evolutionary stages through World War 2.
The 1st Pattern 84/98 was converted from Model 71/84 bayonets; the 2nd Pattern had wood grips, bright blade, and most had flash-guards. This pattern is on first-glance identical to the 3rd Pattern.
The 3rd Pattern comes in any number of variations, but the basic model is as follows: wood, BAKELITE or composition grips, held on by two flush screw/nut sets; short crossguard, no muzzle-ring; steel pommel "loosely considered a bird's-head," T/O slot; push-button/internal-spring latch arrangement. Blades are single-edged, single-fullered (both sides); ricasso is usually marked with either a manufacturer's trademark or a manufacturer code. Blades can either be found "in-the-white" or blued; two-digit date of manufacture may be found on the blade back-edge near the cross-guard.
This bayonet was designed to fit the 1898 German Mauser Carbines and Rifles and their evolutionary variants. Scabbard is sheet-rolled steel, blued, with ball-finial.
