I use three grinds on the Oland tools.
1) standard grind is a 45* bevel with the tip slightly rounded
2) a 70* or so bevel with the tip slightly rounded to get around that angle
from side to bottom in a bowl
3) a 45* bevel with a narrow center and the sides longer. This works best in
3/8 and larger although I have done it on the 1/8 and 1/4" as well. The
sides are ground back about the width of the tool, for example a 3/8" side
on a 3/8" tool and the center 1/8" is gently rounded. I suppose it is
analagous to the Irish grind on a bowl gouge.

The standard grind is the most useful most of the time, however, it is easy
to have a separate tip handy with a different grind.
