Wrenches should lose durability when used to break or pick up blocks.

Do you have any particular reasoning for suggesting this?

It makes the wrench consistent with every other tool.

Disagreed. People will just use a pickaxe.

I also don't believe that this should be implemented. A wrench shouldn't be compared to other tools in minecraft as none of them fit the same description. To also adress realism, IRL your shovels handle will break off, your sword will get dull or crack, but wrenches don't actually experience much wear and last decades.

It already isn't like normal tools due to it being stackable

Thanks for your suggestion, it has been added to our public submission sheet.
