Changing Default Tool Welding

[bitter heart]

In one sentence what I'm trying to achieve is:
"I have a part in my R6 roblox character called "RightPivot" and instead of tools being welded to "Right Arm" I want them to be welded to said "RightPivot""

but further beyond that;
i'm trying to animate tools separately, like the player swings a sword and because it was swung the tool rotates a bit.
Maybe there's a better way to achieve this?
My method of making a new part to weld to just seems so efficient and perfect, I wish it were simple to do this.

You'll have to make scriptable tools

I've made it it's pretty simple
