Very cool, I have a couple of CRKTs including an old 90s era Wrangler and a newer Scribe now that I live in a place you can concealed carry a fixed blade knife. I wisn they were made in the US but that notwithstanding they'd be excellent a prices higher than they command and I really like them.
I'm not a Viking, but this is a tradition I like. I mean, why take chances? The reason they said that giving a knife will sever the friendship is because it is an insult. If you give a knife, you are insinuating that the recipient can't afford to buy their own knife. Therefore, there should be an exchange or a payment to preserve the dignity of the recipient. A friend of mine lost his favorite SAK, a Super Tinker, so I gave him mine and demanded that he hand me a coin in exchange. It didn't matter what coin he gave me, just that he made a payment. We're still friends years later so I guess it worked.
