This is quite rare, and is a very nice example of a Danish Model 1889 Bayonet, intended for use on the Krag–Jørgensen Gevær M/1889 Rifle. This is the original Model 1889 bayonet version, with a checkered leather grip. This was later improved in 1893 with a new version having a wood grips secured by brass rivets. Many were retrofitted, so finding a bayonet with intact leather grips is quite rare.
The bayonet is 13 inches overall, with a 8 3/4 inch long single edged fullered blade. The design is somewhat interesting, with a a triangular lever on the pommel of the bayonet moving the bayonet lock.
Maker W.K.C (German made) marked on the ricasso
The pommel is marked 16859 on one side, probably the serial number of the rifle it was issued with, and 42B. 285. is on the other side, most likely the unit it was issued to. There is also another older crossed out unit marking, and a crown proof on the "crossguard" over 91, for issue in 1891.
