tool grinds

I recall somebody posting a link to some tool grinds on a woodsomething.com site what where they? and I had one to add, its what i use on my sorby bowl gouge(well the schools, but I'm the only one who likes the deep U shape) it started by accident, but I noticed more and more it was getting easier to bore out the center of bowls with that one rather then any of the others, including the pointy one(I do that because I have a tendency to go through the bottom otherwise) a I've started trial and error grinding with it and so far it seems to be pretty good, I grind a steep bevel, but making it almost an angle across the front(longer point on the left)kind of hard to explain, but it curls around at an angle, it works great, less catches, smooth cut, the long left side is good for slicing cuts, and the short right lets me take good heaving cuts without grabbing the edge for a catch, as well as boring easily too, any suggestions as to why I shouldn't keep this? (is it hard on the tool or something like that?)
