Adjustments how?
To sharpen that edge requires an expensive clamp. So unless you have some kind of sharpening service. Where you maintain the scissors of cosmetology, barber, or a sheep farmer.
No one else is going to have the clamp.
(Mom was a hairdresser. Some guy would stop by and sharpen every pair of scissors he was handed. That day, that stop. Out the back of a van. No idea what he charged.)
I'd be happy to do it but it won't cover the cost of the clamp.
