Ted Volrath was a Korean War vet, who lost both legs during that war. He later studied Isshinryu, achieved strong rank and was a leader in the martial arts for the handicapted teaching movement.
He would do demonstrations on defense from his wheelchair, grabbing attackers, diving out of the chair pulling them on the ground and then going for it.
But he once starred in a movie "Pushers Die Hard" (which I never saw, probably a real grade 'z' movie. and they built a special wheelchair for him.
I saw it at a karate show after a tournament in York Pa in 76. He was on the stage talking about the moive, and had the entire audidience stand up.
When he described the scene where the pushers attacked him he grabbed both handles on the wheelchair and pulled them up. Two sawed off shot guns sprang out and fired blanks over the head of the audicence.
Everyone, literally EVERYONE dropped into their seats at the same time in shock.
That always seemed to be a reasonable weapon in a wheelchair to me.
