Nick Set is an electrician in Canada. Here he gives a run-through of his tool bag filled with essential hand tools including multiple sizes of pliers and screw drivers, along with his reasoning behind having them. He carries an array of wire strippers, too – for various wiring tasks. What precision tools does he use and why? There are some surprising items, too – like a putty knife and carabiner. He doesn’t talk about the carabiner specifically; any ideas what he uses it for?
