How to Write 刀 (dāo) — Meaning “Knife; blade”

Imagine the character 刀 looks like a small knife with a curved blade on the left and a straight handle on the right. The downward stroke on the left is the sharp edge, and the hook is the handle. Picture slicing through an apple with this simple shape to fix it in your mind.

Write the left stroke first: a curved downward slash that bends slightly left, then a horizontal hook stroke to the right. The hook should be short and sharp, not too long. A common mistake is making the first stroke too vertical — it should curve like a blade, not a straight line.

刀 (dāo) means 'knife' and is an independent character, while ⺈ is a radical component (often called 'knife top') used in characters like 负 (fù) and is never used alone. 刁 (diāo) means 'tricky' or 'cunning' — it looks like 刀 but has a horizontal stroke through the hook instead of a curve. Always remember: 刀 has a smooth curved blade; 刁 has a crossbar.

刀 appears in everyday words like 菜刀 (kitchen knife) and 小刀 (small knife). It is also part of idioms such as 刀山剑树 (a mountain of knives and a forest of swords), describing extreme danger. In Chinese culture, a knife is often associated with decisive action but also danger — giving a knife as a gift can imply cutting ties, so it is avoided in gift-giving.

Common words containing 刀 include: 菜刀 (cài dāo) — kitchen knife; cleaver; 小刀 (xiǎo dāo) — small knife / pocket knife; 剪刀 (jiǎn dāo) — scissors.
