All tools have combat uses

Like axes can disable shields, I think that other tools should have combat uses as well as follows:

Pickaxes: Take away twice as much durability to gold, iron, diamond and netherite armour. Leather and chain are unaffected.
Shovels: Deal higher damage when landing a critical hit.
Hoes: Deal knockback equivalent to the Knockback I enchantment.

All in all, I think this would make combat more interesting. Of course, not all players would be happy with this, so an option to Disable Tool Combat would have to be available. Thank you for your time.
