Wow! What a great, brilliant, superb, amazing invention!! (oh, and in case I forgot, my zip is 99206).
I have actually had a valve knob come off during a dive. It was on a deco bottle during a class, at 70', and when I went to turn on my stage, the knob was missing! The instructor used his knife to take his deco bottle valve knob off (once he went onto the bottle), and screw it onto mine.
The next day my buddy actually found the knob and spring laying on the bottom at 150'.
