Cuts like a knife...

So I picked up a package from JCPenney's yesterday - an item I bought online at a significant discount thanks to it being on sale and having a coupon. When I went to open the package, I found this notice to not open it with a sharp instrument. I thought that was odd, since the item WAS a sharp instrument - a set of 3 paring knives. I thought these would be decent knives, better than the cheap get-paid-after-rebate ones I have now, but if they need to be protected from other sharp instruments.
