Here we have a nice condition WW1 German 98/05 bayonet, commonly known as the (butcher bayonet).

The blade of this bayonet is in good condition, with a clean surface and retaining a good tip. It features a rare maker’s mark that we don’t come across very often, reading “FERD. ESSER & Co ELBERFELD”, accompanied by the company logo of a rearing horse. On the spine of the blade it is marked with a “W” under a crown, the date 1916 and an inspection stamp,
The wooden grips are in excellent condition showing minimal wear with no visible damage. This model bayonet is equipped with a flash guard and a fully functional rifle-retaining button. Another inspection stamp can be found on the hilt.
The metal scabbard is in good condition, displaying only one minor indentation on its rear that is barely noticeable. The lower ball of the scabbard and the scabbard throat both display inspection stamps.
To finish this bayonet off, it comes with a period-correct brown leather frog. Although the leather shows signs of wear, it remains in solid condition with all its stitching is intact.
This is a very decent WW1 98/05 bayonet with an interesting rare maker.
