A post hole digger is a hand tool used to manually dig deep and narrow holes in order to install posts, such as ones for fences or signs.
A post hole digger can also be known as a clamshell digger, due to its resemblance to the seaside shell.
The tool can vary in appearance but commonly looks similar to two shovels joined together.
It has sharpened blades which pierce the ground on impact, making hole digging easier, and long handles to allow for digging holes of various depths and widths.
The two shovels work simultaneously by digging into the ground to create a hole, and then removing any loosened soil by clamping together.
