Since the title of this thread is "How to Remove Ceramic Finish" I thought i would post the method i used to create a very satisfactory result.
1.) Disassemble the entire knife (This includes removal of thumb stud).
2.) Some say to start at a very coarse grit sand paper (i.e. 120 or so). I say start at a "Fine" grain sandpaper to remove less metal, leave shallower scratches, and make polishing easier.
3.) Sand off all ceramic using a "Fine" grain sandpaper (I used 220). Complete this with forward and backward strokes in the SAME direction.
4.) Move up to a finer grain sand paper (500) and sand in the OPPOSITE direction of the previous step. Sand until all previous scratches are gone and all new scratches are in the same direction.
5.) Continue this method moving to finer and finer grains as high as you can possibly buy. My sanding intervals were: 220 ==> 500 ==> 1000 ==> 1200. As 1200 was the finest i could find in my area. I hear they make up to around 9000, so shop around.
6.a) Once you complete all sanding, eliminating all previous scratches, move on to polishing.
6.b) OPTIONAL: Use "Brasso" to pre-polish all rugged/ackward scratches. Brasso like any polish removes a small amount of metal to leave the surface bright and shiny.
POLISHING TIP: A little trick i picked up in Military School. Use Cardboard (the kind from an old box) to polish. It is quicker and more effective than a rag.
7.) Pick up some "Mother's Mag and Aluminium Polish" from your local Walmart or appliance store. Polish both side to desired shine. The more you put in the higher the shine.
NOTE: The same method can be used to polish up hardware and pocket clip.
good luck and happy polishing
