bowl
棬 centers on a bowl, specifically a wooden one used for holding food or offerings.
棬 combines 木 (tree/wood) with 卷, which likely contributes the sound and may relate to a curved or rolled shape, suggesting a wooden bowl.
The left side 木 is wood, and the right side 卷 looks like something curled or bent. Picture a wooden bowl carved from a curled piece of timber.
For ケン, imagine Ken the carpenter carving a wooden bowl: Ken -> ケン, and his bowl is made of wood.
