A self-defense keychain is a practical item that features essential self-defense tools, designed to help you protect yourself if you find yourself in a dangerous situation on the street.
As a child, I owned a Kubotan. It was a metal object, likely made of steel or an alloy, measuring around 30 cm in length and resembling an oversized pencil. The basic concept is that it can function similarly to a self-defense pen, but it’s significantly larger in size.
Alarm
A personal alarm should be the first thing you think about adding to your self-defense keychain. You can find smaller versions, and there are plenty of varieties available. Some of them function like a grenade, featuring a pin that, when removed, triggers the alarm.
Another option is to simply use a whistle. While an alarm has the perk of not needing to be blown into, both tools are great because they can be quite loud.
