Pointed things have a sharp end, like a cat's pointed teeth or the pointed tip of your #2 pencil . A pointed comment, on the other hand, is deliberately direct.
You might buy stylish shoes with pointed toes or wear fake, pointed fingernails as part of your Halloween costume, but the second definition of pointed is even more common. A pointed remark gets right to the heart of the matter, and might even hurt someone's feelings. If your mom gives you a pointed look, you probably know exactly what she's thinking about.
