George Hughes:

I am not sure, but I think most of the tools that you buy are simply
ground at a flat 45 degree angle, except scrapers which are somewhere
around 60 degrees.

In talking to the Sorby rep, he said that they felt like most people
that bought their tools were not going to use the grind that came with
it (our club has found that to be incorrect) and that all would quickly
grind the tool to the bevel they prefer. However, in club we have found
this takes some time depending on whether you are turning with others,
taking classes, or turning on your own. Turning on you own will take
you longer to decide as you will be limited to your own imagination to
develop your own technique and grind.

If you are not comfortable establishing the "Hughes grind" now, go back
where you bought your tools and measure the angle. Take you digital
camera with you and snap a picture even!

You might be heartened to know that the reknowned Stuart Batty has
decided for his own tools (this was relayed to me by someone that had
dinner with him) he is simply grinding everything at 45 degrees, no
matter what. That way he doesn't keep up with any jigs, settings, etc.
The shape of the grind is different, but the angle is all 45.
