I absolutely love the self sharpening feature in the seven piece block set. I've had many knife sets in the past and always end up having to buy a sharpener down the road and bring it out almost once a month to resharpen knives that were supposed to last a lifetime. this set has a built-in sharpener and every time you draw out a knife it gets a brand new edge! I couldn't give it a better review they're fabulous!
