sharpening a hollow grind?

[80sskater]

I've read it's the same as sharpening a flat grind, is the technique different in any way?

 

[Obsessed with Edges]

At the blade's edge, i.e., the 'secondary' bevels, it's no different than sharpening a flat grind. The 'hollow' in the grind is ordinarily above the bevels, up in the 'primary grind' of the blade, and wouldn't be touched in normal sharpening anyway.

So, sharpen away...
