Short story. I was a British Soldier who was blown up in Afghanistan. I had my ribs broken, all the skin burnt off my left arm up to the point of my body armor. My jaw broken. The skin from my face burns off on the left side and half my hair burnt off. I also lost a singular testicle meaning I can still have kids, fortunately.
I was incredibly lucky. But I did have serious damage to my writing/dominant hand. I lost nearly all use of my thump and my grip strength is not what it should be. But it's never held me back. That is the short story as it would bore everyone if I went on about my ligament damage etc.
Use length to create torque. A small amount of grip strength with long pliers means a lot at the working end. If you don't have room then work around the problem. A clamp on the end of pliers can also work.
I refuse to my limited by my 'disability' and you should as well.
