I learned on WorkSharp, Spyderco Sharpmaker, and DMT Dia-Sharp Diamond stones. All are different, but work extremely well. A little earning curve. Good steel.
Stay safe, healthy, sanitized, and calm.
Leave scales on, clean otherwise, butterfly, grill direct on coals, scales down. I season with cayenne pepper, garlic powder, seafood season, lemon juice with a few slices. About 10 minutes. Check when flacks out of skin.
