I was cutting some beef for stew meat today, and not having much luck with my Son's knife. On a whim I went out and grabbed a Mora knife I recently bought at Smoky Mountain Knifeworks. WOW!! Butter! My question, I know these knives have some kind of edge called Scandi edge? But my only sharpening equipment is an old Lansky setup. What angle should I use on the Mora?
