Chasing the Edge..... :-(

Simply put, grinding jig solve all the problem when you grind thin, wide and long blade .
In fact I would like to watch a video of someone / there are those who claim to do so / how they grind FF bevels on 1.5mm thick Chef kitchen knife free hand ...............

come over anytime, you can watch me do it

These are all free hand. I’m not even a very good grinder, but I’m doing it all the time and eventually you find your way

Depending on what your final blade looks like All the work is in the finishing anyway

You can also finish edges on stones. All of these were finished on stones. It’s keeps everything cool and under control

Jigs don't always help. With a distal taper, the tip is still unsupported and can flex, but it will flex until it hits the back of the jig and then stops. And the blade can still flex spine to edge, too. Or if the blade is past the end of the jig, it doesn't help at all since the blade is flexing with nothing behind it. With a blade that is thin to begin with, the ledge has to be thin as well or the belt will grind the ledge as well as the blade, especially when you put in the distal taper at the tip and are grinding past where the spine is. For thin flexible blades, I found the aluminum channel piece worked much better.

Taz my friend , when you know problems you can find way to solve them This are straightening jigs but just to give you one idea/way how to solve all this problems when you use jig for grinding very thin blade .........
