I’ve read this thread through twice, and just figured out what was bugging me about it...
My reply to the OP’s question is, how have you been sharpening your Scandi grind blade up to now... before the SHTF? At home or in camp, what’s your preferred method? For me (and like some others) a Spyderco double-stuff stone or a dmt double sided stone suffices in the field—mostly because you can hone your edge to keep it from totally dulling. The Worksharp Field Sharpener gives you diamond stones and various ceramic rod grits in one compact package... it’s a winner.
I guess my point is, if you have not had to field hone/sharpen your knife yet... ever... is it really the one you want in a SHTF scenario? Scandi or otherwise. For such instances, I would want the tried and true blade and sharpening tool that I’ve used often in the field, is light weight, uncomplicated, and easy to maintain. I don’t like Scandi grinds, so I can’t speak to that; but for my most used knives, I carry the things mentioned, and reach for a carbon steel blade with either a convex or V edge. Best to have the tools you are most proficient with—especially in a difficult situation.
Hope this helps.
