Well guys, I went back at it today to see if a day's rest would change anything. And, of course, it did. I guess it was a combination of a new rod and finding the right spot on the spine. On mine, the edges seem sharpest up toward the tip. Once I got the rod scrapped down a bit and found the right point on the knife, I'm throwing spark pretty well.
Thanks for all the suggestions. I may still fix up a hack saw blade to carry with me just so I don't bugger up this knife. Did I mention that I love this knife?
