Query: Can never be sharp

I bought this set at great discount. Then so much disappointment. I took out two knives from the set and used them so far. The rest still in the box, and may not ever be used.Of the both knives I used, the feel in the handles is great. However, the blades are so dull. Took the sharpener a while to sharpen the blades, and after just on cutting session, became dull again.Got to get a new set, and willing to pay much more. It will worth the money and less frustration.
