Ninja Knife Block Set NK32010GY1

The removable NeverDull sharpener is the standout feature of this Ninja knife block set: keep it attached for sharpening and stability, or take it off to store it separately and reduce the block’s footprint by up to 35% compared with Ninja’s K12010. The set pairs that flexible setup with rust-resistant German stainless-steel blades and a built-in ceramic sharpening wheel. Its long-term sharpness guarantee is conditional on using and maintaining the knives as directed, so the claim is worth reading with that qualification in mind.

What matters most

This is a set for someone who wants a sharpening system close at hand, rather than a separate sharpener to track down when a blade needs attention. The ceramic wheel is designed to restore the edge, and the block lets you sharpen with the sharpener attached or remove it when you want to store it elsewhere. Ninja says the blades are tested to more than 400,000 cuts and guaranteed to stay razor sharp for 10+ years when used and maintained as directed. Those are manufacturer claims, not a reason to overlook everyday care.

The full-tang, riveted handles are described as balanced and ergonomic, a practical consideration if you spend time slicing ingredients for dinner. For example, reaching for a knife to cut cheese or meat, then returning it to the block, keeps the sharpening system in the same spot. Keep in mind that the 35% smaller-footprint claim applies with the sharpener removed and is measured against the Ninja K12010, the block still needs counter or storage space.

Best use cases

A solid pick if you want a knife set with its sharpening mechanism built into the storage setup and the option to move that mechanism off the counter. The removable design gives it an advantage over a more basic block with no integrated sharpener, especially if you value keeping sharpening gear together with your knives.

It might not be a great match if you’re shopping for a single knife, or if you don’t want a block-and-sharpener setup at all. The listing also doesn’t specify the individual knives included, so shoppers choosing a set around particular knife types should confirm the package contents before deciding.

Tips for day-to-day use

Use the sharpener on the block when you want the added stability, or remove it for separate storage when counter space is tight. The key practical point is that removing it changes the footprint, it doesn’t turn the set into a knife-free storage solution. Keep the sharpening and care instructions in mind, since the stated 10+ year sharpness guarantee depends on use and maintenance as directed.

The blades are described as rust-resistant, not rustproof. If your priority is a low-maintenance set that never needs attention, that distinction matters. This design makes more sense for someone willing to use the sharpening feature as part of regular kitchen routines than for someone who simply wants knives in a block and no extra mechanism.

Before you decide

Can the sharpener be stored separately? Yes. The NeverDull sharpener can be removed from the block for off-counter storage, or kept attached for sharpening and added stability.

What does the 35% space-saving claim compare? It refers to storing the sharpener off the block versus Ninja’s K12010 block, not to a comparison with every knife block.

Are the blades guaranteed to stay sharp for 10+ years? Ninja states that they are, provided the knives are used and maintained as directed. The listing also describes the blades as rust-resistant and tested to more than 400,000 cuts.

Is it worth it?

The case for this set is its combination of a removable sharpener, a built-in sharpening wheel, and rust-resistant German stainless-steel blades. It suits a kitchen where a full knife block is useful but counter space is limited enough that storing the sharpener separately could help. The trade-off is that this is still a block-based set, and the listed footprint reduction depends on removing the sharpener. Choose it if that flexible sharpening setup fits how you cook, look elsewhere if you want a specific knife lineup confirmed in the listing or prefer a simpler, knife-only storage approach.
