For cutting joints and for more precision the best choices would be the tenon saw and the dovetail saw. These are ‘Back Saws’, what are known as because of there steel backs ( the top edges of the saws). The weight of the steel back assist and steady the saw for more precise cuts. The tenon saw ought to be used for cutting tenon joints ( along with general sawing jobs) whilst the Dovetail saw should be used for other joints such as dovetails. For cutting curves and shapes, saws with more teeth are needed. For these jobs you should use bow saws or coping saws. A bow saw consists of a narrowed toothed blade suspended between two long narrow handles that are supported and separated by a narrow rod in the centre of the handles making an H shape. The blade is kept in tension with a twisted cord that is attached to the opposite ends of the handles. The cord is actually twisted using a flat key attached to one loop of the cord. The key hits the centre rod which keeps the cord from untwisting A coping saw consists of a very thin blade stretched between the ends of a C-shaped body to which the handle is attached. The blade is easily removed from its frame, so that it can be passed through a drilled hole in the middle of a piece of wood, reattached, and start cutting from the middle of the piece To cut metal you will need a hacksaw. Hacksaw’s consist of a tough fine-toothed blade, stretched taut in a metal frame. There also are various kinds machine powered saws.

A scroll saw is the powered version of the coping saw, used for cutting intricate curves A jigsaw is used for cutting curves into a piece of wood.

A mitre saw ( sometimes called a drop saw) is a power tool used to make a quick, accurate crosscut in a work piece ( however there are non-electrical versions). It is most frequently used to cut wood, although some plastics and light metals can also be cut with the tool Most mitre saws are relatively small and portable, with common blade sizes ranging from eight to 12 inches. The mitre saw makes cuts simply by pulling a spinning circular saw blade down onto a work piece in a short, controlled motion .
