Spade
Encyclopedia
A spade is a tool designed primarily for the purpose of digging or removing earth. Early spades were made of riven wood.

Designs of spades

Spades are made in many shapes and sizes, for a variety of different functions and jobs. There are many different designs used in spade manufacturing. The term shovel

is sometimes used interchangeably with spade, but shovels generally are broad-bottomed and better suited for moving loose materials, whereas spades tend to be pointed for use as a digging tool.

The most common spade is a garden spade, which typically has a long handle, is wide, and is treaded (has rests for the feet to drive the spade into the ground). An Irish spade is similar to a common garden spade, with the same general design, although it has a much thinner head. A sharpshooter is a narrow spade. A turfing iron has a short, round head, and it used for cutting and parring off turf. A digging fork, or grape, is forked much like a pitchfork, and is useful for loosening ground and gardening. There also can be toy spades for kids.

 using a form of spade called a Loy. It took place on very small farms or on very hilly ground, where horses couldn't work or where farmers couldn't afford them. It was used up until the 1960s in poorer land. This suited the moist climate of Ireland as the trenches formed by turning in the sods providing drainage. It also allowed the growing of potatoes in bogs as well as on mountain slopes where no other cultivation could take place.
