This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
錍 combines 金 (metal) with 卑, which likely contributes sound. The exact historical development is uncertain.
The left side is metal 金, and the right side is 卑. Without a clear meaning, picture a lowly piece of metal whose purpose is unclear.
For ヒ, imagine a piece of metal that makes a soft 'hee' sound when struck: hee -> ヒ, though the metal's use is unknown.
