A Cut Above the Rest: Ninja Foodi NeverDull Knife Set Review
If you love cooking, you know that dull knives can ruin the fun. The Ninja K32012 Foodi NeverDull Premium Knife System promises to change that forever. With its built-in sharpener and sleek German stainless steel design, this 12-piece knife block set is made to stay sharp for life. Let’s find out if it lives up to the hype.
First Impressions
When I opened the box, I could tell right away this wasn’t an average knife set. Each knife felt solid, balanced, and professional. The block itself is modern, with a matte black finish that fits beautifully in any kitchen. But the best part? The built-in sharpener. It’s cleverly hidden in the block, making sharpening easy and fun.
Ninja claims that their NeverDull Technology keeps knives razor-sharp for over 10 years. That’s a bold claim — and one I was eager to test.
Design and Build Quality
The Ninja K32012 Foodi NeverDull Premium Knife System comes with 12 pieces, including:
- 8″ Chef Knife
- 8″ Slicing Knife
- 7″ Santoku Knife
- 5″ Utility Knife
- 3.5″ Paring Knife
- Six 4.5″ Steak Knives
- Built-in Sharpener and Knife Block
The knives are made from German stainless steel, known for its strength, rust resistance, and precision cutting. The ergonomic handles give a firm grip without slipping, even when your hands are wet. The knives feel balanced — not too heavy, not too light.
Each blade glides through meat, veggies, and bread with ease. No squishing, no tearing — just clean, effortless cuts.
Ninja’s choice of German stainless steel is no accident; this alloy is prized by professionals for its specific balance of hardness and flexibility; you can read a full breakdown of culinary steel types and blade maintenance at culinarypro.com.

Performance and Sharpness
Here’s where the Ninja K32012 Foodi NeverDull Premium Knife System truly shines. The blades cut through tough items like sweet potatoes and raw meat with zero resistance. After weeks of daily use, I didn’t notice any dulling.
When I finally tested the built-in sharpener, I was amazed. Just a few swipes in the slot, and the knife felt brand new. The sharpener uses a unique wheel system that sharpens at the perfect angle every time. No guesswork needed.
Unlike most sharpeners, this one doesn’t scratch or wear out your knives. It feels smooth and professional, just like what a chef would use.
Ease of Use
One of the biggest wins of the Ninja K32012 Foodi NeverDull Premium Knife System is convenience. Whether you’re slicing, dicing, or chopping, these knives handle it all with ease.
The built-in sharpener saves time — no need for extra gadgets or electric sharpeners. Plus, it’s safe to use. You can sharpen a knife without removing it from the block, keeping your hands away from the blade.
Cleaning is also easy. Though they are not dishwasher safe, a quick hand wash with warm water and mild soap does the job. The blades don’t rust or stain easily, even after cutting acidic foods like tomatoes or citrus.

This knife set is perfect for:
