It's not intelligence my student, it's experience. Something I shall try to impart upon you ^^
Correct, if you shape the win correctly you can slice through almost any obstacle. To shape the wind so it cuts you will have to use your chakra to compress the wind currents so that they are thin and sharp. If you don't shape the wind to slice through as obstacle, depending on its size, the wind will go around whatever is in it's path.
So overall, wind is a free flowing element that can be compressed in order to cut through almost anything.
