When you’re using electric power tools, it’s easy to get carried away and yank the plug out of the extension cord socket, possibly leaving your powerless saw or drill lodged inside whatever you’re working on. You can avoid the pitfall by tying the cords in a knot.
The tip comes from A Concord Carpenter in a two-year-old post that’s recently started making the rounds via Reddit. The author advises holding both ends of a cord together, then looping them in a loose knot before connecting them. The knot takes the strain away from the plugs, preventing an untimely disconnection.
