Every new ski will usually be sharp tip to tail including those areas on the tip/tail above the effective edge that will never hit the snow. Those sharp edged tips will hit the other top sheet during moguls etc and cause the chipping.
You just have to find the widest points on the tip and tail(end of effective edge) and dull/round the edges with a file and diamond stones if you have them at a 45 degree angle.
Put a flat edge or file against the ski and you will see the spot when the tips/tails get narrower and there is space between the straight edge and tip/tail. Mark with a piece of tape on all 4 sides and then round the edge above that on the tip and behind that on the tail. Above the red line on this picture of one of my ski tips.
