A narrative might center on a protagonist wielding a seemingly useless blade, who subsequently discovers unconventional methods or inner resources to achieve victory.
Works featuring implements with diminished cutting ability provide a unique lens through which to examine character development and narrative innovation. This approach can subvert expectations within the action and fantasy genres, allowing for exploration of resilience, strategic thinking, and the value of unconventional approaches. The historical context draws upon Eastern philosophical traditions that often de-emphasize brute force in favor of discipline, skill, and mental fortitude.
