Ok, so the question is, if say a Fallkniven F1 comes with the blackish ceracoat stuff on the steel, will it still give a shower of sparks similar to the uncoated F1 version from the swedish army firesteel by using the squared off spine to strike with. Or are the results quite poor??? I've had 2 ppl give me a completely opposite answer so far, perhaps you gents and gentresses can help.
