Hi , I am after basic sharpening stone system for knives to take into the field. I use a 2 sided bahco file for machete/axes and after preferably just one other lightish weight item to handle large bladed scandi knives, and occasionally kitchen knives at home at possible?( save buying multiple items). I looked at the fallkniven DC4 and Diafold which seemed perfect size wise but then heard diamond setups are are not the best for scandi grinds. Thanks for any other suggestions.
