According to tactical considerations, what is a critical distance to maintain from an edged weapon assailant?

Maintaining a distance of 30 feet from an edged weapon assailant is considered critical due to the reaction time and distance needed to effectively respond to a potential attack. The rationale behind this tactical distance is rooted in the understanding that an assailant armed with an edged weapon can cover ground quickly, and 30 feet serves as a buffer that provides time to assess the situation, react, and potentially deploy defensive measures.

In practical terms, the distance gives an individual the opportunity to react in one of two ways: either to escape to safety or to prepare for engagement if necessary. This distance reflects both the effectiveness of the assailant's weapon and the typical reaction time for an individual to recognize a threat and respond accordingly. Therefore, 30 feet is deemed optimal to mitigate the risks involved in close-quarter encounters with an edged weapon.
