Took apart my first dryer with a butter knife and a prayer, now I roll in with a $6 bit driver
Back when I started doing appliance calls in my uncle's van in Modesto, I'd pry open a dryer panel with whatever was in my pocket and hope nothing snapped. Now I keep a magnetic bit driver with a 1/4 inch hex and a headlamp, and the same job takes me 4 minutes instead of 40. What's the one cheap tool you wish someone had handed you on day one?
