Ave! 

Just one look at this super-pointed tool lends you to believe that this is not for you... Again, you'll have to trust me. :-) Do not be decieved by the very scary point. I remind you again that this tool is dusted with a very fine 600 diamond grit. This is the VERY BEST  tool that you will ever find for superior detail cleaning for ancient coins...bar none!

IT WILL NOT HARM YOUR COIN'S PATINA! 

It will take practice, but you'll be amazed and very satisfied with your final result. I use this tool for my final detail-work on legends, exergues, portraits and reverse details.
