You can also buy lathe tools ground to 60 degrees for metric and American 
threads and 55 degrees for Whitworth and BSF.     These come in high-speed 
steel and brazed-on tungsten carbide.

Look at the Chronos and Arc Euro Trade catalogues on the web.

I am pretty useless at grinidng tools, especailly those with a critical 
profile.   Until you get adept at grinding, i suggest that you buy one of 
these and try it out.

The 'pen-knife' goodie is a thread guage, which enable you to indentify 
existing threads.

Hope that this helps

Cheers!   Hubert
