I'm kind of a knife collector, so it depends on the knife. If it looks good to me, I'll pay whatever I think fair.

The highest I've paid for a folder is $350 each for a Strider GB and an AR.

The highest for a fixed was about $300 for a Busse custom.

I have a Cold Steel Mini Culloden (plain edge) that is a great Sgian Dubh.

Still searching for a more traditional model...
