Making items unbreakable?

I'm sure there's already a way of doing it however if there is I can't find any plugins/posts about it. If someone could link me it would be very appreciated

 

I do this.. for RepairBench (for example)..

Code:

object OnEntityTakeDamage(BaseCombatEntity entity, HitInfo info)
{
    if (entity?.GetType().ToString() == "RepairBench")
        info.damageTypes.ScaleAll(0.0f);
    return null;
}
