As much as I love scandinavian blades, a dedicated survival knife needs to be robust IF it is called upon to perform duties normally carried out with more appropriate tools. Mors Kochanski is probably the greatest exponent of the humble Mora, but Mors also uses an axe in his woodland, resource rich area of expertise. The best course for buying a knife is to sit down and figure out just exactly what it is your going to modify in Nature for your needs. Sometimes a Mora is just fine. Sometimes you want more.
