To better preserve the expression of martial skill within the competition environment, and to address low-threshold weapon configurations that may be exploited for mechanical advantage, future equipment restrictions will move beyond simple minimum and maximum weight limits toward a more comprehensive formula-based evaluation system. Starting this year, the competition rules will introduce a new “Weapon Dynamic Coefficient” as part of the equipment inspection standards.

Previous regulations primarily focused on weight limits. However, through practical observation in competition environments, we have found that weapon handling characteristics are influenced not only by weight itself, but also by factors such as point of balance and overall length proportions. Some weapons may comply with existing regulations while still gaining a significant handling advantage that can affect competitive fairness and the technical expression of martial arts.

The following formula will therefore be introduced as part of the evaluation process:

Weapon Weight × Point of Balance ÷ Overall Length (tip to pommel)

Through this coefficient system, we aim to more comprehensively balance handling differences between weapons, reduce the impact of rules exploitation and equipment-based advantages on match quality, and encourage competitors to place martial skill itself at the center of competition.

Detailed coefficient ranges and related equipment regulations can be found in the tournament rules.
