Support BladeForums! Paid memberships don't see ads! For those who sharpen using a system like the edge pro, how do you protect your carbon steel knives from scratches AND corrosion/tape stains? I'm actually using a Hapstone with AO stones which require water, and I've stained carbon steel knives while using tape in an attempt to protect from scratches. The tape traps moisture against the blade. I'm considering heavily waxing the bevel or oiling before using masking tape.
