Spades and shovels - each has a different purpose. The pointed ones, (known as roundnosed), are for digging holes in harder ground, like exposing a leaking water pipe. The pointed end pierces the compacted soil more easily than does a flatnosed spade. The flatnosed blade you'd use in the garden, where soil is generally looser and easier to penetrate. It's also a better shape for trenching, as when preparing the gound for planting leeks, for example. Shovels are used for moving loose materials such as coal, sand, or gravel, and have turned-up edges to stop the stuff from spilling off the sides. Not the best shape for digging. For the garden, I'd go for a flatnosed blade. They come in various blade sizes, the smaller ones often being referred to as 'ladies spades'. Often the cheaper ones are better value. I've found that those made by Yeoman are of good quality, and not too expensive.
