All your slicing, dicing and chopping needs are covered with this 17-piece knife set from Ninja. Each knife in the set is forged of German stainless steel with a full tang and bolstered construction for enhanced balance and strength. A sharpener equipped with NeverDull technology is built into the block to enable easy, foolproof sharpening. Simply insert a knife into the sharpening slot and swipe the lever. A stone sharpening wheel engages the blade at the perfect angle and applies optimal pressure to restore the edge to razor sharpness.
