What is the disadvantages of tenon saw?

Well, honey, the disadvantages of a tenon saw are pretty simple. It's not great for cutting curves or intricate designs, and it can be a pain in the butt to use on smaller pieces of wood. Plus, if you're not careful, you could end up with a wonky cut that'll have you cursing up a storm. But hey, if you're just looking to make straight cuts for tenon joints, it'll do the job just fine.
