Torque sticks are the devil's tool, I swear. My old mentor had a set that was supposedly calibrated but we checked them against a real torque wrench once and they were all over the place. He'd been using them for years and wondering why he kept having to replace wheel bearings. I had my own wake up call when I snapped a stud on a customer's F-150 and had to pay for the whole hub out of pocket. That was the day I bought my own clicker and started treating it like gold. Dropped it once too, and you better believe I sent it in for a check before using it again.
