A tactical pen can be used for self-defense in several ways. Firstly, the pointed end of the pen can be used to strike an attacker in vulnerable areas such as the eyes, throat, or groin.

Additionally, the pen's design often includes a textured grip, which can be used to apply pressure to sensitive areas or to create leverage in a self-defense situation.

Additionally, nerves are often very small and thin, making them difficult to see without the use of specialized imaging techniques. Overall, while nerves are not inherently invisible, they are often not easily visible without the appropriate tools or technology. **
