The high carbon, high rockwell Moras are about the ONLY off the shelf knife you can spark with flints. Softer steels merely let the flint edge gouge into the seel. A hard steel will result in a carbon molecule(s) percussing into a spark. This is one reason I stash multiple moras in my kits in reserve ( along with being inexpensive and off the shelf sharp.) True, you will eventually pit the spine. But remember this is essentially duplicating a flintlock firearm and they fired hundreds of rounds along with messy blackpowder. You may want to dress the spine with a file to get a squared surface and some 'bite' for the flint to connect with. The laminated Frosts can be successfully used this way also after preparation. Now it's back toETS to moderate some argument over the ultimate survival knife
