Trimmable Tools
Trimmable Tools is a mod (and soon datapack) that allows you to trim your tools!
Description
Using the existing smithing templates, you can apply fancy trims onto your tools. In version 2, each template gives a unique set of patterns, so there's 18 possible patterns per tool!
In total there are 5400 combinations of tools, trim patterns, and trim materials! Resource packs that modify the tool textures will work with them as well.
Datapack v2
The datapack version of v2 is still in progress and will be released once it is ready.
