serratus anterior
the key features of a tenon saw is the shark jagged teeth at the bottom of the saw to cut your wood.
Sawtooth means a jagged edge, that would look similar to the jagged teeth of a saw. Therefore, a sawtooth rim of the hills, is a jagged edge on the rim of a hill or mountain.
Sierra is a Spanish word meaning 'saw'. Since a mountain range resembles a saw with the mountains forming the teeth, it also figuratively means 'mountain range'.
The name Sierra means 'mountain range' in Spanish. It specifically means a mountain range with jagged peaks.
the leaf shape is jagged edges almost in the shape of a chain saw
It will have bigger teeth or less teeth per inch and should have a wider set to the teeth.
It is the displacement of teeth on the saw, i.e., to bend the teeth of the saw alternately to either side of the blade. ( then I noticed this is in a computer section, sorry).
Insects and birds have no teeth.
