For spindle turning it is easier for me to roll beads and cut coves with a flat grind or even a slightly convex grind.
a micro bevel is an easy way to undo the concave grind
on my small 3/8 diameter bowl gouge I use a michelsom grind - a convex bevel. Great tool for hollowing small openings.
I hone skews a concave grind makes it easier for me to hone. I hone many many times before regrinding a skew.
my bowl gouge I use from the grinder with a concave bevel. for hollowing I grind off the heel To make a partial micro bevel.
bevel drag is the enemy of a clean cut. The flat, convex, and micro bevel have less bevel drag.
the convex bevel makes the cutting edge want to cut a little deeper and it increases the bevel drag slightly.
