My primary kit knife is a F1 Fallkniven too.
The painted wood handle moras are still sold. I took one apart after it was ruined ( nephew with an electric kitchen sharpening monstrosity. The rattail tang sort of floats in a large hollow in the handle secured in the back by a crush fit roller pin and up front by the sheet metal ferrule. And there are large gaps into which water and crud can flood in.
They were all of $8 when I bought several. I've given some to hiking companions who never owned a knife, freaked seeing me with one, freaked again when some small wreck occured and the knife resolved things and wanted a knife NOW. Always encourage new converts. One wound up lost in horse tack and emerged rusty. i cleaned it up and it works fine. 2 remain in my secondary kits, rehoned to even better edges, oiled and sitting in those wretched sheaths that actually work.
