You can damage the stone by not rotating it during use and not using the whole of the surface of the stone, causing a curvature on the face of it. Not a problem if all your knives are exactly the same size and shape. You can, and most probably will, with inexperince put a ‘wire edge’ on the knife. It will seem sharp but the edge wont last.
Best advice would be to buy a good steel and learn to use that. A multicut or an oval steel.
