Using objects around you as weapons in a fight can enhance your self-defense capabilities, but you also need to pay attention to safety and legality. Here are some tips and suggestions: 1. **Observe your surroundings**: Before a fight, quickly assess your environment to see what objects you can use as weapons, such as chairs, books, keys, bottles, etc. 2. **Use heavy objects**: Many everyday objects can cause damage under the action of gravity, such as a bottle of water or a metal object. You can throw these objects at your opponent or use them for melee attacks. 3. **Sharp objects**: If you have sharp objects available (such as keys, scissors); you can use them to stab, but make sure to use them at an angle and force to effectively attack. 4. **Create obstacles**: Use objects such as chairs and tables to block the opponent's attacks, or use them against multiple opponents. 5. **Cover yourself**: If you can find a large object (such as a backpack or clothes), you can use it as a barrier to protect yourself while looking for an opportunity to fight back. 6. **Use long objects**: Objects such as umbrellas and sticks can be used as weapons. Their length allows you to attack while keeping your distance. 7. **Be safe and legal**: In any case, using an object as a weapon may bring legal liability, and ensuring the safety of yourself and others is the most important thing. 8. **Choose the right moment**: Attacking the opponent unexpectedly at the moment when they can attack can often increase the chance of success. It is important to pay attention to protecting yourself and others when practicing, and make sure not to use these techniques in non-self-defense situations. Always consider self-defense within the scope of safety and law.
