Sorry to hear of your accident mate, I've just come back from Falmouth, a nice 500 +m2 job that I did for my brother and his business partner, the reason I'm telling you this is because his partener lost an arm 2 years ago in a car accident. You wanna see this guy go, he has a prostetic limb from just below the elbow with twin metal hooks that look and work like your middle and index fingers. There isn't much he can't do, very few exeptions, chin up mate
