[Woodcarver] Double beveled chisels..as recommended by Chris Pye

[TWWOODWORK at aol.com]

Carving chisels are not usually sold with a double beveled edge. What  Chris 
Pye is referring to is to sharpen your carving tool (chisels and  gouges) in 
the usual fashion, and then sharpen the back or inside edge  so it curves down 
to the edge from the usual sharpened side. Usually, this  secondary bevel 
equals about 10 to 15% of the length of the first sharpened  side, and is at an 
angle of about 10%.   
    The advantage of this is you can turn the chisel or  gouge over and cut 
with the secondary side down as well. For instance, if  you were to carve 
grapes, you can turn the gouge upside down and hone the grape  so that the edge 
will cut in the same direction as the shape of the grape.
    I have put a secondary bevel on most of my carving  chisels and gouges. 
Learned this from Chris Pye when taking a course in relief  carving in Maine. 
You will find this sharpening method used mostly in England  and rarely find it 
on the continent of Europe.???????
    Hope this helps.
