It tops our ranking with 9.5 out of 10. No. 1 of 10 in our [knife sets ranking](https://vettedten.com/kitchen/knife-sets/) · Updated November 2026 · [How we rank](https://vettedten.com/how-we-rank/) **9.5 out of 10** · Best Choice The Ninja K32006UK is a six-piece knife block with a sharpener built into it. It suits cooks who want sharp knives on the worktop and would rather swipe a lever than learn a steel or whetstone. Why it's here: - Integrated sharpener in the block, so keeping an edge needs no separate steel or stone - Three 20cm knives (chef's, bread, slicing) plus utility, paring and scissors - Owners report the knives arrive very sharp and cut cleanly through tomatoes and meat - 10-year edge guarantee when registered and used with the sharpener Keep in mind: - Hand wash only, so it cannot go in the dishwasher - Owners say the block feels lighter and less well made than the knives, and the slots hold blades loosely - The sharpener is not for the serrated bread knife - The sharpener takes metal off the blade each time, so edges wear down over the years [Check price on Amazon](https://www.amazon.co.uk/dp/B09WYZ4CNS) ## Why the Ninja K32006UK scores 9.5 - How happy owners are: 1st of 10 - How many rated it: 2nd of 10 - How new it is: 4th of 10 ### Why No. 1 beats No. 2 The Ninja Foodi StaySharp Knife Block with Integrated Sharpener K32006UK (9.5) beats the ZWILLING Gourmet 7-pcs Knife block set with KiS technology 36133-000-0 (9.1) because it leaves owners a little happier and is the newer design. ## About the Ninja K32006UK The set has three 20cm knives (chef's, slicing and bread), a 13cm utility knife and a 9cm paring knife, plus kitchen and herb scissors. The blades are German X50CrMoV15 stainless steel. They are full tang, with a double rivet handle and a half bolster. The cutting angle is 22 degrees. The sharpener sits in the block, in a drawer that can be removed. Slide the lever to the bottom, put a clean knife in the slot, then move the lever up and down about ten times. The sharpener uses a ceramic wheel. Ninja recommends sharpening every two weeks, or when a knife feels dull. Two items are off limits to the sharpener: the serrated bread knife and the scissors. The block has suction cups underneath to hold it steady while you sharpen. The scissors come apart for cleaning. Ninja says to hand wash all the knives to protect the edge. Its 10-year guarantee applies when you register the product and use it with the StaySharp sharpener. ### Key specs - Pieces: 5 knives plus kitchen and herb scissors - Chef's, slicing and bread knives: 20cm each - Utility knife: 13cm - Paring knife: 9cm - Steel: German X50CrMoV15 stainless - Construction: Full tang, double rivet, half bolster - Cutting angle: 22 degrees - Care: Hand wash only - Guarantee: 10 years, when registered and used with the StaySharp sharpener ## What owners report about the Ninja K32006UK Owner feedback for this exact model is thin on the retailer pages we could open, so this is a short picture rather than a firm verdict. Owners of the K32006UK describe the knives as good quality, well balanced and very sharp on arrival. Several say the knives have stayed sharp so far that they have not yet used the sharpener. Those who have tried it call it easy. Some bought it as a gift or to replace a blunt old block, and say the set looks good in the kitchen. The one complaint we found was a seller error: a set that arrived without the scissors. Some owners also wondered whether they could have found a better price. We found no owner threads on how the knives wear after months or years of sharpening. ## Who the Ninja K32006UK suits It suits households that want one block covering everyday jobs, and people who know their knives go blunt but never get round to sharpening them. The lever makes upkeep quick. Remember the bread knife is serrated and sits outside the sharpener, and sharpening removes a little steel each time. Look elsewhere if you want to put knives in the dishwasher, or if you want steak knives. The Ninja StaySharp 13-Piece Knife Block Set & Removable Sharpener covers a bigger range. For a sharpening slot for each knife, the Tefal EverSharp Pro 6-Piece Knife Block Set K297S744 is another option. ## Questions about the Ninja K32006UK ### How do you sharpen the Ninja K32006UK knives?

We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 25 models for this guide before settling on these ten. Brands can't pay to be included or to move up. We last checked these picks in November 2026.
