title: Iron Tooth (鐵齒) — Six-Harmony Mantis
---

**鐵齒 (Tiě Chǐ, "Iron Tooth"** — also **鐵刺 "Iron Thorn"** / **鐵叉手**) is the **first of the six core sequences (六趟)** of [**Six-Harmony Praying Mantis**](https://wulin.openmindspace.org/six-harmony-mantis) in the **張詳三 (Zhang Xiangsan)** Taiwan line. It is the entry form, installing the branch's soft-entry-then-hidden-hard method and its core hand vocabulary: the throat-lock (鎖口), the three-grab mantis (三把螳螂), the trigger-release hand (撥機手), and the rolling-linking hand (轉連手).

## What it trains

- **鎖口 (throat-lock)** — the branch's signature seizing-and-shutting entry
- **三把螳螂** — the "three-grab" mantis hands that recur through the curriculum
- **Soft contact, hidden hardness** — yielding on touch, the power released from within
- **The shared closing** — like all six sequences, it ends 進步跺腳 → 破膝 → 掛耳圈

Six-Harmony movement names are descriptive and run longer than the tight four-character Seven-Star style.
