How shovels are made

On a cheap shovel, the socket that grips the handle is just a tab of the blade rolled into a ring.

The short version

A stamped shovel usually starts as one flat blank of cold-rolled sheet steel, blade and socket together. Presses dish the blade and raise a stiffening rib, the tab is curled into a ring, and a rivet through that ring grips a wooden handle. Forged shovels take a costlier route, hammered from hot steel so the metal thickens where the load falls.

Blank the flat sheet

A press cuts one flat outline from cold-rolled sheet steel, with a long tab above the blade. Whatever gets trimmed away on either side of that tab goes to scrap.

Goes in
Sheet steel
Dish and rib the scoop

Dies curve the blade and raise a standing rib at the back of the dish, which stiffens the thin sheet. The rib leaves a hollow on the underside where mud and clay can collect.
Curl the tab round

The tab is rolled into a circle to make the socket. It normally stays unwelded, so nothing holds the ring shut until a rivet goes through it.
Weld on a back plate

Mid-grade shovels get an extra flat plate welded over the hollow on the back. This adds rigidity and leaves a smooth face that soil cannot cake onto.

Sheet steel
Plug the gap

A piece of wood usually fills the space between the handle's end and the blade. Without it, the thin metal there can collapse when someone levers with the tool.

Goes in
Lumber
Seat the handle

A wooden handle goes in with its grain lined up vertically for strength. Its end is notched so it can flex to follow the curve of the neck.

Rivet it through

A hole drilled through the ring takes a rivet, which locks the handle in and keeps the socket closed.

Worth repeating

In the Neolithic age and earlier, the shoulder blade of a large animal was often used as a crude shovel.
Forged shovel blades are thin at the digging edge and grow thicker toward the handle, a variation stamping cannot match.
Where a stamped socket meets the foot tread there is only a single thickness of sheet, and that spot is a known place for shovels to rip under heavy load.
