I've killed a few through 'normal' handlding. CMOS chips are pretty resilient now days but power fets are still susceptible to static shocks, even the kind that you don't feel. There are so many factors that determine an indivudal persons static shock risk and the environment they're in is a big part of ti, so some people will have a golden touch and some iwll have a 'black' touch =)
Also Speakerguy, do you store your fets properly like in conductive foam or do you just toss them in a plastic drawer? Makes a big difference.
