Noita's Tool Tinkers

This update is just a re-do of some sprites I didn't like, but more will come eventually!

Version 1.1 Changelog:

• Updated pack.mcmeta, as I forgot to do it in 1.0 and used a placeholder instead. Oops.
• Updated sprites for:

1. Copper Sword, making it slightly shorter
2. Iron Sword, polishing its shading and giving it a different hilt
3. Diamond Sword, polishing its shading and removing the little diamond gem from the hilt
4. The entire Netherite Toolset, making the shading less harsh, and removing the little indent from the Netherite Sword to make it more uniform with the Diamond Sword
