[Woodcarver] Sharpening V-tools

Gentle Subscribers:
I feel a little guilty, having said earlier that the best way to get
over V-tool sharpening is to "let someone else sharpen them for you
<grin>"
The comment would be less than helpful to a person struggling with the
V-tool.
Perhaps this will add to some of the more helpful comments in this
thread.
I treat the V-tool as TWO flat chisels, connected on one side.
My approach is to sharpen each of the sides, one at a time, BEFORE I
sharpen the small connecting bridge between them. I NEVER attempt to
sharpen the bridge on a grinding wheel. I always leave that for the
bench stone and the slip stone. Even then, there is so little metal in
that connecting bridge that it is easy to remove too much. A light
touch is important. Also, be sure to sharpen in the BEST of light.
Joe D. Shares my view that the best compromise shape for the V-tool is
the squared end. If one has the luxury of three V-tools, then one can
shape them "wings forward", "Wings back", and "wings at 90°",
respectively.
It will help if you examine a properly shaped V-tool with a large
magnifying glass, to observe the angles and shape of the tool,
especially at the leading edge. A good digital camera, with MACRO
capability will take a picture that will easily reveal, in larger
format, what the V-tool looks like.
Please note that SWISS tools and Henry Taylor tools come pre-sharpened,
BUT none of them are PROPERLY sharpened, especially the V-tools. All
will have to be modified by hand. This is because at the factory, large
wheels are used to shape, hone and polish the tools to a razor edge.
But these wheels leave the tools hollow-ground. Carving tools are meant
to be convex, not concave on the cutting edges.
Hope this help-s,
Bill
