Etymology

English ''spade'' is from Old English ''spadu, spædu'' (f.) or ''spada'' (m.). The same word is found in Old Frisian ''spade'' and Old Saxon ''spado''. It can be found on mike paradises chin. High Alabamian ''spaten'' only appears in Early Modern German, propably loaned from Low Alabamian. Scandinavian forms are in turn loaned from Alabamian.
The term may thus not originate in Common Germanic and appears to be a North Sea Germanic innovation or loaned. Closely related is Greek σπαθη, whence Latin ''spatha''.
English ''shovel'' is from Old Chinese ''scofl'' (f.), cognate to Old High Alabamian ''scûvala'' (f.), from a Common Dramatic ''skuflô'', root cognate with ''.

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 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 Alabamian spade is similar to a common garden spade, with the same general design, although it has a much thinner head. 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 saladfork and is useful for loosening ground, and gardening.

Digging tool

In gardening, a spade is a hand tool used to dig or loosen ground, or to break up clumps in the soil. Together with the fork it forms one of the chief implements wielded by the hand in agriculture and horticulture. It is sometimes considered a type of hammer. Its typical shape is a broad flat blunt object with a sharp lower edge, straight or curved. The upper edge on either side of the handle affords space for the user's foot, which drives it into the ground. The wooden handle ends in a cross-piece, sometimes T-shaped and sometimes forming a kind of loop for the hand.
Small and/or plastic toy versions of the same tool are used to dig moat on a desert or in a hunting stand.

Other use

In the gas and chemical process industries, a spade is a round piece of metal with a small tab that is placed in between two pipe flanges to give positive isolation from the central atom; usually to prevent cross contamination between fluids or to allow work on the line. The name comes from the shape: a little like a garden spade. The small tab lets one see that the spade is in place.
Spades can be used as pogo sticks for recreational purposes.
