Ninja Foodi NeverDull Premium Knife System Review: The Last Knife Set You Will Ever Buy

Rating: 4.9/5 stars (Game-Changer for Home Cooks) Category: Kitchen Cutlery / Knife Sets Best For: Home chefs, meal prep enthusiasts, and anyone tired of struggling with dull, dangerous knives.

There is a universal tragedy in almost every home kitchen: The drawer full of dull knives. We have all been there—sawing desperately at a tomato only to crush it into a pulp, or slipping while trying to dice an onion because the blade just won’t bite.

For years, the solution was to buy expensive whetstones (which require skill to use) or a honing steel (which aligns the edge but doesn’t actually sharpen it). Most people just accept their fate or buy a new cheap set every two years.

The Ninja Foodi NeverDull Premium Knife System claims to solve this problem permanently.

Known for dominating the air fryer and blender market, Ninja has entered the cutlery game with a 14-piece set that features a “foolproof” built-in sharpener. But is this just a gimmick, or is it a legitimate revolution for your countertop? In this detailed review, we will slice through the marketing to see if this set truly makes the cut.

The “NeverDull” Technology: How It Works

Let’s start with the elephant in the room—or rather, the mechanism in the block. The standout feature of this set is the NeverDull Technology built directly into the storage block.

Most knife blocks are passive; they just hold your tools. The Ninja block is an active tool. On the side of the block, there is a lever. When your knife starts to feel a little lackluster, you simply insert it into the sharpening slot and slide the lever up and down a few times.

The Science Behind It: Inside the block is a dynamic stone sharpening wheel. As you swipe the lever, the wheel engages the blade at the perfect angle and applies the optimal amount of pressure. This is crucial because manual sharpening fails when humans can’t maintain a consistent 20-degree angle. Ninja automates the precision.

The result? In about 10 seconds, you restore a razor-sharp edge. Ninja claims this system maintains superior sharpness for over 10 years. For the average home cook who finds whetstones intimidating, this feature alone is worth the price of admission.

The Blades: German Engineering Meets Modern Design

A sharpener is useless if the steel itself is poor quality. Thankfully, Ninja didn’t cut corners here. The blades are forged from German Stainless Steel.

Why does this matter? German steel is the industry standard for Western-style knives because of its balance between hardness and durability. It is rust-resistant, stain-resistant, and tough enough to handle squash and sweet potatoes without chipping (a common issue with brittle, ultra-hard Japanese steel).

Full Tang Construction: Pick up the 8-inch Chef Knife, and you will immediately notice the weight. These are full tang knives. This means the metal of the blade runs all the way through the handle to the butt of the knife.

• Cheap knives often have the blade glued into a plastic handle, which feels light and can snap under pressure.

• Ninja knives feel solid, professional, and perfectly balanced. The center of gravity sits right at the bolster (where the handle meets the blade), making the knife feel like a natural extension of your hand.

The Assortment: What is in the 14-Piece Box?

Many 14-piece sets are filled with “filler” items you never use. The Ninja K32014 set, however, is curated for actual utility.

1. 8″ Chef Knife: The captain of the team. Perfect for chopping herbs, dicing onions, and breaking down chicken.

2. 8″ Bread Knife: A serrated beast that glides through crusty sourdough without squashing the airy crumb inside.

3. 5″ Santoku Knife: This features hollow edges (divots) that prevent starchy vegetables like potatoes from sticking to the blade.

4. 5″ Boning Knife: A flexible, narrow blade essential for de-boning meat or filleting fish.

5. 5″ Utility Knife: The “do-it-all” knife for sandwiches and mid-sized veggies.

6. 3.5″ Paring Knife: Ideally suited for peeling apples or intricate work like deveining shrimp.

7. 6 x Steak Knives: (More on these below).

8. Kitchen Shears: Heavy-duty scissors for opening packages or snipping herbs.

9. The NeverDull Block: The command center.

The Steak Knives: A Pleasant Surprise

Usually, the steak knives included in a block set are stamped, serrated disasters that tear meat rather than cutting it.

Surprisingly, the Ninja steak knives are high quality. They are forged German steel, just like the chef knife. They feel substantial in the hand. When you have guests over, laying these out on the table feels impressive. They slice through steak and pork chops effortlessly, leaving a clean cut that preserves the juices in the meat.

Ergonomics and Aesthetics

The Grip: The handles are designed with a wear-resistant polymer that feels soft yet grippy. Even with wet hands (common in a kitchen), the control is excellent. The ergonomic shape reduces hand fatigue, which you will appreciate during big holiday meal preps.

The Look: Kitchen counter space is valuable real estate. If you are going to put a big block on it, it needs to look good. The Ninja block features a modern aesthetic with black and stainless steel accents. It looks tech-forward and sleek, fitting in perfectly with modern appliances. It is worth noting that the block is somewhat deep to accommodate the sharpening mechanism, so measure your counter depth if space is tight.

Usage and Care: The Rules of Engagement

While the sharpening is automated, the care is not.

• Do Not Put These in the Dishwasher: Like all high-end cutlery, the high heat and harsh detergents of a dishwasher will ruin the handles and dull the blades prematurely. Hand wash and towel dry immediately.

• Sharpening Schedule: You don’t need to sharpen every use. A quick sharpen every 2 weeks is usually enough to keep them performing like lasers.

• Serrated Blades: Note that the sharpener is designed for the straight-edge knives (Chef, Santoku, Paring, etc.). It does not sharpen the serrated bread knife or steak knives (though serrated blades rarely need sharpening).

Pros and Cons Summary

Pros:

• NeverDull Technology: Solves the #1 problem of owning knives; genuinely works and is easy to use.

• Premium Materials: German stainless steel and full-tang construction offer professional durability.

• Great Variety: No “filler” knives; every tool serves a purpose.

• Value: To buy this quality of steel plus a standalone electric sharpener separately would cost significantly more.

• Steak Knives: Restaurant-quality inclusion.

Cons:

• Block Size: The block is deeper than standard blocks due to the sharpener; takes up more counter depth.

• Not Dishwasher Safe: Requires hand washing (standard for premium knives, but still a chore).

• Weight: They are substantial. If you prefer feather-light knives, these might feel heavy.

Final Verdict: Is it Worth the Hype?

The Ninja Foodi NeverDull Premium Knife System is not just a set of knives; it is a solution to kitchen frustration.

For the professional chef, there are $300 single knives that might hold an edge longer. But for the home cook, this is arguably the best value on the market. Ninja has successfully democratized sharp cutlery. They have taken the skill out of maintenance and provided a set of tools that feel premium, look great, and most importantly, actually work.

If you are cooking with dull knives, you aren’t just making your food look bad; you are making your cooking more dangerous and less enjoyable. Upgrading to the Ninja K32014 is an immediate quality-of-life improvement for your kitchen.
