Olsen O.K. Throwing Knives

[CNW180]

I have a set of Olsen O.K. throwing knives passed down from my grandfather that i know nothing about? Can anyone give me any background on the things. I dont even know where to post something like this. Havent had much luck with google.

Thanks in advance,
Craig
