[1.12.2] How do you return a item from crafting table with damage?

Hello! I'm new, I just joined, I started modding a week ago or so and I don't have a good understanding of java but I'm working on that.

 

I'm trying to make a recipe so the player can craft 3 leather from one saddle and a pair of shears, returning the shears with 4 damage and consuming the saddle.

The recipe needs to be able to use shears with any damage. I have read about wild cards and item containers but all those threads were old.

 

I made a mod pack once and use CraftTweaker to make my own custom recipes using scripts and I loved it and wanted to try my hand at modding. I really don't know what I'm doing though; I don't want to just copy and paste code but I'm sure if I saw it I could figure it out.

You won't be able to accomplish this without writing some Java. Water buckets (milk buckets, lava buckets) all return a "container item" when used in crafting because that's already been coded in. Vanilla has not applied the same logic to tool-like items in order to make them take damage. Any mod you've seen that does that has added that functionality themselves in the Java code.
