An etching needle is used to draw through hard ground or to scribe a line directly into a metal plate when making a drypoint. Anything with a sharp point can be used as and etching needle to a degree. However, not all scribes are created equal. Holly Morrison's preferred needle is a carbide tipped needle--terrific for drypoint. The image to the right illustrates a variety of etching needles. From left to right they are:
a diamond tipped needle

The needle can be sharpened on the sharpening stone by rotating it with a push and pull motion. Be careful not to blunt the needle when sharpening.
Scrapers
Scrapers come in a variety of lengths and sizes. The scraper is used for reducing an area of a plate. The scraper is a very effective tool for manually removing a mark on the plate. the scraper will leave marks on the plate which are can by reduced with sand paper and then a burnisher.
Taping of the scraper shaft allows the scraper to be held more comfortably and firmly while working. first aid tape works best for this purpose. The scraper needs periodically sharpened on a sharpening stone. All three sides of the scraper should be razor sharp. The edge of the scraper can be maintained by using first the coarse, then the smooth side of a sharpening stone.
Burnishers come in a variety of shapes and sizes to facilitate the nature of an area--from small to large--that needs to be attended to. Agate burnishers are also available as they are quite hard and can be manufactured in a variety of shapes. Be careful not to drop an agate burnisher.
The burnisher may need periodically polishing of its surface with emery cloth.
It is beneficial to use engraver's copper when engraving. It is evenly milled and cuts smoothly. One can engrave zinc and industrial grade copper, but because of its uneven resistance when engraving it is difficult to learn on.
