Product description
The Ninja K32017 Foodi NeverDull Premium Knife System solves the most common frustration in any kitchen — dull knives — by building a professional-grade sharpener directly into the storage block, so your blades are always razor-sharp without any extra effort.
NeverDull Built-in Sharpening System
The defining feature of this set is the NeverDull Technology built into the knife block itself. To sharpen, simply insert any knife into the sharpening slot on the side and swipe the external lever — a dynamic stone wheel automatically engages the blade at the perfect angle and applies optimal pressure to restore a razor-sharp edge in seconds. No guesswork, no separate sharpening tools, no skill required. Ninja designed the system to maintain superior sharpness for over 10 years of regular use. After three years of daily use, long-term reviewers confirm the knives still perform like new.
German Stainless Steel Blades
Every knife in the set is forged from premium German stainless steel, which is known for exceptional durability, rust resistance, and edge retention. The blades feature a full-tang construction — the steel extends through the entire handle — giving each knife a professional, well-balanced weight in hand. The cutting angle is precision-engineered so blades glide effortlessly through tough ingredients, whether you’re breaking down a whole chicken or paper-thinly slicing tomatoes.

Comfort and Handle Design
The handles feature an ergonomic, chef-approved design with triple-riveted stainless steel accents that provide a secure, confident grip during extended prep sessions.

Real-world users consistently highlight the lightweight feel and non-slip grip as standout comfort advantages.

The storage block features a modern black and stainless steel design that complements any kitchen décor without taking up excessive counter space. The block stores all 17 pieces securely in dedicated slots, keeping knives safely accessible and protecting the blade edges between uses.
