Here we have a Resource Pack for Minecraft (Java Edition) 1.14 - 1.19.2 (adjust pack_format number as needed)

This pack contains 4 models, each implemented using custom data as to not override any of Minecrafts existing features. All swords use the base stats of the diamond sword, but can easily be changed to suit your needs (manual included).

(Summon Commands included)
