   Hello again all   
      
   Is there such a thing as a "scribing divider" ?   
      
   Useful for when working on "black" steel?   
   Will cut-through / mark the mill-scale surface?   
      
   Maybe about 10inch/250m to 12inch/300mm "legs".   
      
   If I recall rightly I have seen dividers where each leg has a smallish   
   about 3mm very hard steel/carbide cylinder ground to a point.  Which   
   can be demounted/unclamped and resharpened.   
      
   If so, what are these known as?   
   Not doing well looking in tool catalogues.   
      
   Else - is the answer something else like dividers with a point at one   
   end yes, but a chalk / soapstone at the swept end?   
      
   Regards,   
   Rich S
