hammer, mallet
槌 centers on a tool for striking: a hammer or mallet, used to deliver forceful blows.
槌 combines 木 (wood) with 追, which likely contributes the sound. The character originally referred to a wooden hammer or mallet.
The left side is wood 木, and the right side 追 suggests chasing or driving. Picture a wooden mallet chasing a peg into place: 槌 is a hammer.
For ツイ, imagine a hammer striking with a sharp 'tsui!' sound: the impact noise cues ツイ while the wooden mallet drives the point home.
