About
The character 硎 is a phono-semantic compound, with the semantic radical 石 (shí, "stone") on the left indicating its material category, and the phonetic component 刑 (xíng) on the right providing its pronunciation. Its primary meaning is a whetstone, a grinding stone used for sharpening blades. This core sense is featured in the literary idiom 发硎新试 (fāxíng-xīnshì), which metaphorically describes a newly sharpened blade or a young person testing their fresh skills in the world.
