Shovel: Sheet Steel Blade, Folded Socket, Riveted Ash Handle
A hand shovel is a sheet-steel blade with a fold at the back that makes a socket for the handle and stiffens the blade. The wooden handle, usually ash, is riveted into the socket, and a T-piece at the top gives grip. Cut and dish the blade, fold the socket hot, shave an ash handle and rivet it in.
