I have alway’s just taken them to Marion live bait where they get exchanged or I wait for them to get sharpened. The ole boy who is 85 years old that does the sharpening may be hanging up the practice after this year. Good Luck {John}
Both Gander and F&F have replacement blades, so I think I’ll just run over today and get a new set. That will allow me to experiment some with the old blades and see if I can figure out how to sharpen them up.
