Ninja Knife Block Set, Stainless Steel

The integrated StaySharp sharpener is the defining feature of this Ninja knife block set: it is built into the storage block, so you can maintain the blades at home without storing a separate sharpener. The set includes five knives for different kitchen tasks, plus scissors, giving you a ready-made selection for everyday preparation. Its forged German stainless-steel blades and double-rivet construction are intended for regular use, while the block keeps the pieces together on the worktop. It suits you if you want a broad set with sharpening built into its storage, a simpler set without this mechanism may suit you better if you have little worktop space.

Quick overview

The six-piece collection comprises a chef knife, bread knife, slicing knife, utility knife, paring knife and a pair of scissors. The three larger knives have 20cm blades, the utility knife is listed as 13cm and the paring knife as 9cm. The block has an integrated sharpener, and the total set weighs 2.46kg. Its listed dimensions are H32.1cm x W18.92cm x D36.5cm, so it is worth considering where it will sit before choosing it.

The range of blade types is useful when you move between tasks: use the bread knife for a crusty loaf, the paring knife for smaller trimming jobs and the chef knife for general chopping. That is more adaptable than buying a single all-purpose knife, though it also means finding space for a substantial block rather than keeping just a couple of knives in a drawer.

On-body feel

Ninja describes the handles as ergonomic and designed for comfort during extended use, and the double-rivet build points to a solid, conventional knife design. There is no handle material or individual knife weight specified, so it is difficult to judge the feel in the hand from the details alone. The overall set weight is 2.46kg, but that figure covers the full collection rather than telling you how each knife balances.

Ten in mind that an integrated sharpener is convenient, but it makes the block itself part of the sharpening system, if you prefer to sharpen knives using your own method, that feature may matter less. From the way it is set up, the appeal is an organised home station rather than a compact, minimal storage solution. You may want to skip it if you need a particularly small block or only want one or two specialist knives.

Tips for day-to-day use

Keep the block somewhere accessible before deciding whether the full set will work in your kitchen. Its listed height and depth can make placement a practical consideration, particularly on a crowded worktop. For a typical meal, the chef knife can handle general chopping, while the bread and slicing knives give you alternatives for cutting a loaf or portioning larger items. The utility and paring knives cover smaller jobs, and the scissors add a separate tool for tasks that do not call for a blade.

Follow the included use and care guide: the stated 10-year replacement guarantee applies upon registration and when the knives are used as directed. This is a replacement guarantee, not a claim that care or registration can be overlooked.

Before you decide

What is included? Five knives, scissors and a block with an integrated StaySharp sharpener.

What are the blade lengths? The chef, bread and slicing knives are listed as 20cm, the utility knife is 13cm and the paring knife is 9cm.

How does the guarantee work? Ninja states a 10-year replacement guarantee upon registration, subject to use as directed in the use and care guide.

Final verdict

This set makes most sense if you will use several knife types and want their storage and sharpening combined in one block. The task-specific selection is more useful than a basic two-knife purchase for varied food preparation, but it asks for more worktop space and brings an integrated sharpener you may not need if you already have a preferred sharpening setup. Choose it for an all-in-one home arrangement, look elsewhere if compact storage or a smaller selection is the priority.
