Query: great at the beginning but lots of chipping within 6 months

I was ambivilant about this knife when I first got it- the grip is not very ergonomic or comfortable- but I fell in love with it because of its performance. Unfortunately, within 6 months of heavy household use (no dishwasher, no dropping on the floor, no cutting on anything but cutting boards) this knife developed several sizeable chips that have been very difficult to sharpen away. It has been relegated back to the chopping block for most potential applications in my kitchen.
