You can also make money from the skill by crafting and selling sculptures and furniture at the woodworking bench. Having fully upgraded objects makes a sim’s whole experience more pleasant.

Upgraded objects are really useful because they often give you happy buffs boosting your chosen emotion. The handiness skill is a really useful skill in the sims 4 – not only does it speed up the rate at which you fix broken objects (and reduce the chance of electrocution as your skill progresses) but it allows you to upgrade all kinds of object to improve their functionality and even make some of them unbreakable.
