I am researching hand saws and want to know what the difference is between a compass/keyhole saw and a drywall saw.


The one on the left is a compass saw and the one in the right is a drywall saw.

Hi

well the keyhole saw was designed for just that to cut key holes for door locks, the characteristics are that they will have a very fine toothed blade for cutting wood.

now the drywall saw althoufh similar in appearance has a much more coarse tooth structure and is designed for prepominantly cutting plaster board in the course of dry lining.

Keyhole saw can refer to a lot of saws with a blade the shape of which you see in your Photo's. The difference being is the metal the blade is made from along with the pattern and set of the teeth. If you try and cut plaster board with a blade that is designed for wood it will cut it but will blunt very quickly.

Keyhole also implies as DaveO said is also designed to cut small apertures into what ever material the blade is configured to cut
