If you sharpen/grind the back spine of the Mora into a hard 90* edge, it should be able to be used as the main scraping/sparking tool for the ferrocerium rod. I've done that to a couple of my Moras and the difference is incredible with way more sparks than supplied striker. I've also been told that it works well with natural flints as well. You could drill a lanyard hole in the handle as well.
It would need to be a carbon Mora for natural flint as the spark is made up of the knife steel, not the rock?
