This has been an interesting discussion which has very little connection to my way of keeping my chisels sharp.
It is clearly true about being easier to freehand sharpen a hollow ground blade. Though to do so it requires one to have a grinding wheel to create a hollow grind.
One of my favorite chisels, a Karpenter 1" socket chisel came to me with a hollow grind. It hasn't required any power grinding since it arrived. After years of use, any remnants of the hollow grinding have been honed away.
It just seems funny of the contrast between a chisel from the land of hollow grind has a flat bevel and there is a discussion of the merits or sacrilege of a hollow grind on a chisel from the land of flat bevels.
Sharpening discussions are the political discussions of woodworking.
