Go with one of the Mora knives with the Scandi grind and you will be amazed at the aharpness and how strong the lightweight, laminated blade is. I really like my Frost's Mora knives, an exceptional value. I have a bunch of expensive knives and the Mora will perform along side any of the others!
Cost for a Mora, about $12. The sheaths are junk, but you can either make one or buy a custom one for a small fee.
