This notion is believed to have originated from the potential harm that could be inflicted on the person who opened the knife if it were to be closed by another. To avoid any potential bad luck associated with closing a pocket knife that someone else has opened, it is advisable to present the knife to them in an open position.

This way, the recipient can open and use the knife as needed and return it in a closed position, with the blade safely tucked away. By following this practice, one can demonstrate respect for superstition while also ensuring the safe and proper handling of the knife.

A pocketknife also referred to as a jackknife, folding knife, or EDC knife is a type of knife that features one or more blades that can be folded neatly into the handle. This design makes the knife compact and easy to carry in a pocket, hence the name “pocketknife.”

The origin of the superstition surrounding the Knife Rule remains uncertain, but it has gained traction online since the 2010s. Recently, the belief has experienced a surge in popularity on the social media platform TikTok, with numerous users discussing and demonstrating the practice.
