I worked as an assistant mechanic for a few years, and it was a running joke that if something took me more than 15 minutes, the head mechanic probably had a tool to do it in 1.
It's incredible how much a good tool helps, and it really goes to show the difference between a rookie and a master even when they are both doing the exact same job by reading the steps from a sheet that tells you what to do.
I'd reach for a socket, he'd grab my arm and hand me a ratcheting wrench knowing I'd need it before we even cracked open the hood.
I'd try to unscrew a stuck phillips head screw from a rotor, he'd stop me and hand me a tool which you put in the screw and hit with a hammer and it gets it unstuck.
I'd start trying to pry an exhaust off, he'd hand me a blowtorch, tell me to heat it for like 15 seconds, then hit it with a hammer and watch it fall to the ground.
