The coating on my BK7 is badly scratched and worn off in a lot of places as a result of regrinding and all around hard use by its previous owner. So, I want to remove the rest of the coating and give it as nice a satin finish as I can using only hand tools. Anyone have a good idea on how to remove the coating and satin the blade? I'm thinking 400-600 grit sandpaper and maybe steel wool, but I'm no expert. Suggestions appreciated.
