What's the best snow shovel?
It turns out out be a coal shovel. As Tim Heffernan notes at Slate.
In 1911, Frederick Winslow Taylor published The Principles of Scientific Management, the seminal work of the now ubiquitous field. Taylor used empirical methodology to improve business’ efficiency and profitability, and one of the first objects of his study was the shoveling of coal and other common industrial materials. At the Bethlehem Steel plant, he measured the tonnage shifted daily by handpicked “first-class men.” At the time, they were using standardized shovels that scooped between 5 and 40 pounds per load, depending on the density of the material they were working with. But the ideal shovel, Taylor determined, would scoop 21 pounds, be it of coal, pig iron, or anything else. At that weight, a first-class man could shift 59 tons in an eight-hour shift—a nearly four-fold improvement over the 16 tons per shift that Bethlehem then averaged. The company quickly adopted “8 to 10 different kinds of shovels … each one appropriate to handling a given type of material” and varied in size to scoop the standard 21 pounds.
For Bethlehem Steel, the effects were dramatic. It was able to reduce its workforce of shovelers from between 400 and 600 to just 160. Its labor costs per ton shoveled dropped from 7.2 to 3.3 cents. Its profits accordingly soared.
Workers, too—the ones who were left—saw an improvement in their absolute earnings, from $1.15 to $1.88 per day. But, quite sensibly, many of them didn’t feel particularly blessed. For nearly quadrupling their workload, they had increased their earnings by barely more than a half measure.
So what brand and size is actually the perfect snow shovel? I have no idea, but apparently it's one that scoops 21 pounds of whatever needs scooping. Some possibilities here.

My own dirt-digging shovel is the Ames Pony with D-handle available from AM Leonard or Amazon.
