劅 is a rare character whose exact historical development is uncertain. It visually combines 蜀 and 刂, but the original semantic and phonetic roles of these components are unclear.
With no clear meaning, focus on the shape: 蜀 (a region or silkworm) beside 刂 (knife). Imagine a knife used in the ancient Shu region, but treat the meaning as unknown.
For タク, use the sound of 'tack' as in a thumbtack. Picture a knife (刂) pinning a silkworm (蜀) to a board like a tack: tack -> タク.
