THE JOBSITE — Efficiency is a great thing, but it sometimes comes at the expense of quality. For example, those of you who had a paper route in your youth probably learned how important it was to maintain your speed at all times. The newspaper ended up on the lawn? Good enough — just keep going. Newspaper landed in a flower bed? Too bad, you've got to keep pedaling.

If you were to stop for every newspaper delivery error on a paper route, you probably wouldn't get home until dinnertime. So tough decisions were made, and quality sometimes suffered.

But there's a difference between a poorly placed newspaper and an actual safety risk, which you'll see in this video.

{#embed} Wow. I'm not a saw expert, so there's plenty I don't know about the tool in this video. But it seems extremely dangerous to leave a big blade whirring around while you work on other things. Maybe it saves you a few seconds, but it's just a bad way to get stuff done.

I am going to suggest a new rule of thumb for this guy: Never let your power tool crawl around, unattended. That seems like a standard on which we can all agree.
