In an emergency, it is feasible to use the items around you for self-defense, but the following principles must be emphasized: **Legal compliance, non-fatal priority, and only used in self-defense. The following provide some transformation ideas that are in line with the safety and legal framework, but please always take getting out of danger as your primary goal, and give priority to seeking police help. --- ###**Safety tips：** 1. **Legal risks**: Different regions have different definitions of ”weapons", and arbitrary modification of items may violate laws (such as regulations on the control of knives). You need to understand local regulations in advance. 2. **Division of responsibilities**: Self-defense is passive defense, and excessive use may be regarded as offensive behavior. 3. **Give priority to escape**: The ultimate goal of any tool is to buy escape time, not confrontation. --- ###**Self-defense application of daily necessities (example)** #### 1. Key/pen -**Usage**: Hold the tip of the key or the tip of the pen tightly, with the sharp end facing out, and use it to poke the attacker's fragile parts (such as eyes and throat). -**Note **: Avoid excessive modification (such as sharpening metal keys) and maintain their “daily use” attributes. #### 2. Long-handled umbrella/trekking pole -**Usage**: Stab the opponent's abdomen or knees with the tip of an umbrella; swing horizontally to create a distance. -**Enhanced effect**: Choose an umbrella with a metal umbrella head, but do not install sharp parts without permission. #### 3. Backpack/handbag -**Usage**: After being filled with heavy objects, it can be used as a shield to block, or quickly swing to force the opponent to retreat. -**Tactics**: Throwing items in the bag (such as coins and cosmetics) to interfere with the opponent's line of sight. #### 4. Belt/data cable -**Usage**: Quickly pull out the belt and wave it, the metal head can increase deterrence; the data cable can be slapped or wrapped around the opponent's wrist. -**Restrictions**: Certain skills are required, and close combat is not recommended. #### 5. Spray type (legal premise) -**Alternatives**: Perfume, toilet water, anti-mosquito spray (local legality needs to be confirmed). -**Usage**: Aim at the opponent's face and run away immediately after spraying. #### 6. flashlight -**Option**: Strong light tactical flashlight (legal and concealed). -**Usage**: Strong light hits the eyes directly to cause blindness, and the metal shell can enhance the hitting power. --- ###**Absolutely taboo** -**Modification of sharp/explosive materials**: Such as glass stopper blades, nails, etc., may constitute intentional injury. -**Imitate the appearance of a weapon**: If the item is disguised as a firearm, it can easily cause misunderstandings or legal issues. -**Actively provoking use**: Any tool used in an attack may be held accountable. --- ###**Safer suggestion** 1. **Daily preparation**: Carry an alarm (high decibel buzzer) and positioning equipment with you. 2. **Environmental awareness**: Avoid night routes or dangerous areas and plan escape routes in advance. 3. **Learn self-defense techniques**: Mastering basic liberation skills (such as breaking free of wrist grip) is more reliable than tools. Please keep in mind: **Risk prevention is far better than passive response**. In an emergency, staying calm and calling the police (such as China 110) is the highest priority.
