I love these type of knives. When I was working in Madrid I literaly blew two weeks wages on navajas at Cuchillería Simón (one of the cities oldest cutlery shops). But it turned out all right, a girl I worked with offered me to stay at her place and I ended up dating her for a few years.
I need to get a bloody camera and take some new pics. I keep breaking them.
For your next purchases, take a look at Nontron, Zvord peasant and Douk-douk knives. The Zvords are wicked cool, and you need a friction folder!
Here are a couple of my friction folders, made by a friend.
