Hello and thanks to both of you for the replies. Alain can you tell me more about those tools made from old taps and reamers, ? what kind of taps? the reamers I take it are jewelry reamers. I want to start using my et on bone and ivory but the sharpening process is still a challenge, what type of stone is best, not mediocre but best? thanks once again.

I have worked all my life as a maintenance engineer in a steel factory , where the made steel wires ,

all my taps and reamer came from the trash bin ,

most of the taps are long shank taps , 5 , 6 , 8 , 7 ,10 mm , as well as the reamers , adjusted by a electric grindstone ,

No jewelry reamers , too small and fragile ,

 

For sharpening, I use diamond plates sharpening , coarse , fine , extra fine , https://www.google.b...m=isch&imgdii=_

and a old carborundum stone ,

razor-sharp edge, use a honing compound , power Honing system , http://www.toolpost....ng_systems.html

or a other honing compound , https://www.google.b...iw=1483&bih=894

The ezra bowman gravers I found on german e-bay a decade ago , only the steel chisels ( 20 pieces) without holders , for 20$ ,

the curved chisel can be used ,when there is a bending , (pothole ) slope in the workpiece ,

Now on e-bay , ezra bowman gravers , http://www.ebay.com/...nc&LH_PrefLoc=2
