I am fortunate to clock in every night at midnight and work for 8 hours and operate and grind, sharpen tooling. Not as fin as it sounds
So I was able to pull some scrap out of the bin and make my own.
But there are many places out there that manufacture these small tools for such jobs. And there is even a thread with information with many links for tool manufacturers. Here is the thread that Jay started (Chuck's (CRFultz) idea ): http://vectric.com/forum/viewtopic.php?t=278
And I've just done a search on micro tooling and added it to the above thread.
