Worksharp is up to it, but I like a little more freedom to move my blade.
I've heard a few guys complain about boogering up their tips when they get to the end of their draw out of the machine.
Plus the primary grind on the FMv14 is a little different and thick with that central ridge-- I'm not sure how that'd feed into that guide and interface with the sanding belt.
I've used my harbor freight 1 x 30 belt sander to pretty good effect. I can't make my jobs look professional like Josh, but it's ok for beaters.
But for major regrinds/reprofiles or blades I want to look nice, I leave it to the pros.
I orient mine like this for edge-trailing grinding, with my bright light overhead it's really easy to see when I'm raising/chasing my burr
