Hi everyone,
I have only recently started using a firesteel (or, "ferrocerium rod" is you prefer). In using it with my knife, I noticed that the firesteel scratches and damages more than I expected the sharpness of the spine of the knife (see pictures below). More than normal because I think that I would have to sharpen the spine with some sandpaper after every 2-3 uses. Is this normal?
By the way, I've observed a similar thing even when using a different knife...
