switcher blades
A lightweight Fabric mod that automatically swaps the player’s dominant hand when attacking.
About this Mod
This is a lightweight client-side Fabric mod for Minecraft 1.21.x that automatically switches the player’s dominant (main) hand whenever they successfully hit an entity.
The purpose of this mod is to introduce a small but noticeable combat variation. Each time the player lands a hit, the main hand swaps, creating a dynamic and slightly unpredictable fighting rhythm. The mod does not add new items, blocks, entities, or gameplay systems - it only modifies the player’s active hand behavior during combat.
