saw (cuts wood)
鋸 centers on a toothed cutting tool: a saw used for cutting wood.
鋸 combines 金 (metal) with 居, which likely contributes the sound キョ. The character originally referred to a metal saw.
The left side is metal 金, and the right side 居 looks like a saw's teeth resting on a surface. Picture a metal saw cutting through wood.
For キョ, imagine a saw cutting through a giant key: key -> キョ, and the metal teeth bite into the key.
