25 or 30 years ago, I ended up with a 1" ratchet no one ever claimed from the lost and found on a job, I tossed it in a drawer and forgot about it. When I had to take the axle nut off my Sprint, I remembered it, I got it out, intending to buy a large metric socket to fit it. It had a 1 9/16" socket on it, which just happened to be the exact SAE equivalent of the metric size on the axle nut, what's the chances?
