I recently became interested in collecting pocket knives. I was raised in Howard City, Michigan and came to understand that the Olsen knife company was producing knives there. Obviously because of sentiment I was thinking of collecting a few Olsen knives. I have not been able to find a price guide that has Olsen knives and I see on Ebay that some Olsen knives go for a pretty good amount and some do not. Which do I pick? Is there a Olsen knife expert out there that can give some info?
