For an effective polishing tool, the Belgian Yellow Coticule 6x1.5”, Standard Grade is what you'll need. 

FEATURES

• Use wet or dry or wet with a slurry
• 8000 grit (without a slurry), 6000 grit (with a slurry)
• Slurry sold separately 
• Splash stone with water before use
• User friendly and suitable for beginners 
• Non-porous stone that does not require pre-soaking
• The difference between the standard and select grade coticules lies only in their appearance. Both stone grades have identical sharpening qualities. 

TO USE

• Very hard stone (harder that most artificial wet stones) but will still need lapping before first usage and from time to time.
• To lap: Use a lapping stone (i.e DMT-8C 325 coarse diamond sharpening stone or Norton Lapping Stone) or with sandpaper on a very flat surface (i.e. glass). 
• Tip: the long edges of the stone should be rounded slightly with a lapping stone or sandpaper. This way the risk of denting the blade in a normal honing motion across the stone is greatly reduced.

MATERIALS

• Natural sharpening stones
