bamboo tube, wooden peg, spout
梘 centers on a hollow wooden object used for channeling or holding: a bamboo tube, a wooden peg, or a spout. The common idea is a wooden conduit or connector.
梘 combines 木 (tree/wood) with 見, which likely contributes a phonetic element. The character is used for wooden or bamboo implements, but the exact historical development is uncertain.
A wooden 木 object that lets you see 見 through it, like a hollow bamboo tube or a spout. Picture a wooden peg that channels water like a spout.
For ケン, imagine a wooden peg used by Ken to fix a bamboo tube: Ken -> ケン, and he uses the peg to connect the spout.
