The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
The Ninja Foodi NeverDull is the most polarizing pick in the pool. On the positive side: Best Buy verified-purchase reviewers (a high-trust retailer signal) praise "exceptional sharpness" and the convenience of the built-in sharpening system, and the set averages 4.8 stars across 1,100 Amazon reviews. The integrated knife block with a sharpening mechanism is the standout feature reviewers come back to.
What reviewers liked
- Best Buy verified-purchase reviewers (high-trust) cite exceptional sharpness
- Built-in sharpener is the most-praised convenience feature in reviews
- 4.8 Amazon star average across 1,100+ reviews
- German stainless steel construction with comfortable handles per r/chefknives
- Premium-feeling block design noted by multiple reviewers
Where it falls short
- r/sharpening calls the NeverDull system fundamentally flawed, calling it "Alwaysdull"
- r/TrueChefKnives warns micro-serrated edges can't be properly resharpened
- At ~$300 it's the priciest set in this roundup
- Long-term edge maintenance limited compared to traditional knives
- Community trust is much lower than the retailer-review trust would suggest
The Ninja Foodi NeverDull is the most polarizing pick in the pool. On the positive side: Best Buy verified-purchase reviewers (a high-trust retailer signal) praise "exceptional sharpness" and the convenience of the built-in sharpening system, and the set averages 4.8 stars across 1,100 Amazon reviews. The integrated knife block with a sharpening mechanism is the standout feature reviewers come back to.
The pushback is loud and worth surfacing. r/chefknives, r/TrueChefKnives, and r/sharpening all criticize the "NeverDull" concept, with one widely-quoted comment warning that knives marketed as never-dulling typically rely on micro-serrations that "can't be sharpened" once worn. The trust-weighted synthesis: for a household that wants a convenient, attractive block set and won't be touching a whetstone, the high-trust Best Buy reviews suggest real satisfaction. For enthusiasts planning to maintain and resharpen knives over decades, the community warnings are credible.
