How to Write 刃 (rèn) — Meaning “Blade; edge of a knife”

Imagine a knife (刀) with a small dot or line on its edge to show where it is sharp. That extra stroke is like a pointer saying "right here is the blade." This helps you connect the visual of a knife plus a mark to the meaning of "blade edge."

The first stroke is a horizontal left-falling stroke (横撇), then the second stroke is a hook-like curve (竖钩), and the final stroke is a short dot (点) inside the blade area. Common mistakes include making the dot too large or placing it too far from the knife shape — keep the dot close to the inner curve to show the edge.

刀 (dāo) means "knife" as a whole tool, while 刃 (rèn) specifically means the sharp edge of a knife. ⺈ (折) is a component that looks like a bent hook and has no relation to knives — it appears in characters like 乐 (lè, music). So 刃 contains a dot to highlight the edge, which neither 刀 nor ⺈ has.

刃 is used in words like 刀刃 (knife edge) and 利刃 (sharp blade), often describing the cutting part of a tool. It also appears in the idiom 迎刃而解, which means a problem is solved easily, like a bamboo splitting as soon as the knife touches it. Though not common in daily speech, 刃 is important for understanding weapon or tool-related vocabulary.

Common words containing 刃 include: 刀刃 (dāo rèn) — Knife edge; blade; 利刃 (lì rèn) — Sharp blade.; 迎刃而解 (yíng rèn ér jiě) — to be easily solved; to be split as soon as the knife touches it.
