We still use those in the industry for framing up and boring wood utility poles. They're a whole lot easier to carry in than a gas drill or having to rely on battery powered cordless drills for when it counts sometimes. Boring bits carefully kept in an oiled tool cloth and sent up in a nose bag never tossed about or thrown. When I started to apprentice they were the norm. Break one of those out now and the grunts will start to look out their phone or need an energy drink real quick.
I also made a long bit up for drilling deep holes in half stocked muzzle-loading rifles. A brace is better than a drill motor to avoid splits or holes that wander off center when driven to quickly. Haven't used it for a while though. A socket brace is good for some things. Still keep one for some things and pretty handy sometimes, surprised to see them being discussed here.
