This is a knife I aquired recently from a friend who is serving in the Danish Army.
He informs me that it is used by the Swedish SF and as you can see the blade should be familiar to those who know the Swedish Mauser 1896 bayonet.
They have used the blade of the bayonet and fitted it to a wooden handle and scabbard. the bayonet is all metal and would freeze in the hand ,wood does not. They wear it to the front of the belt and high.
I have not been able to research this any further so any help appreciated.
It looks quite a nice knife.
