Replace vanilla iron sword repair item with custom one

Hello, long time reader first time poster, currently developing a mod that changes how tools are repaired/crafted.
Just wondering if I can replace a vanilla tools properties lets say an iron sword uses an ingot to repair, but I have a custom ingot I want it to use instead. I was curious if there is a simple solution I'm not seeing, I haven't found anything on the forums yet so thought id ask myself. Any and all help is appreciated!
