Step 1. Use a respirator.
Step 2. Grab 220 & 400 grit sandpaper. Also find some gray & white scotch brite pads.
Step 3. Tape up blade to protect your knife & yourself ( i didnt...shame on me) & put in a soft sided vise.
Use a scrap piece of leather as a backer to the sandpaper.
Here, always go up/down never side to side.
Move along to the 400 grit.
Grab a small scrap piece of wood,micarta or whatever you have that is hard sided & roughly 2 x 1.5
Here I have the sandpaper flush w/ the top of my backer. I am only taking less than a ½ stroke.
Done w/ the 220 grit
Through the 400grit & scotch brite.
Wiped down w/ a little Howards Feed-n- Wax.
