the Swedish Frost knives are almost in universal use over here, very good and cheap enough to by them 5 at a time................so no upset if (when!) you lose one!
Yeah, bought one at a gas station for some 50 sek ( around 5-6 €) this summer, been using it a lot. Comes in a plastic "sheath", and very easy to sharpen.
Well, actually bought around 8 and brought them as presents for fellow hunters¡¡
