Tool Durability if Hit any Collider

I would like to create Durability for my tools and weapons.

I would attach to a script to my Tool : Tool "health" which is going to be decrease when hit anything what has Collider. CurrentHealth = MaxHealth- hardness Is that possbile somehow ?

Other script is attached to e.g. Tree Where there is a float hardness which affects the tool "health

I use UFPS . Any Idea? Thank you :)
