U+7870 "硰" CJK Unified Ideograph-# Unicode Character

U+7870 "硰" CJK Unified Ideograph-# is a rare or obscure Chinese character that typically appears in historical or classical texts rather than modern usage. Its composition combines the radical for "stone" or "rock" (石) with a phonetic component, and its meanings often relate to grinding, whetting, or sharpening stone implements, although precise definitions can vary by source and historical context. This character is part of the CJK (Chinese, Japanese, Korean) unified ideograph block, encoding a logogram shared across these writing systems, though it is seldom encountered in everyday language and is more frequently found in specialized dictionaries or ancient literature.
