Ninja NeverDull 17-Piece Knife Block Set with Built-in Sharpener — Our Honest Review
The single biggest reason home cooks end up with dull knives is that sharpening feels like a chore — something you keep meaning to do but never quite get around to. The Ninja NeverDull solves that problem by building the sharpener directly into the knife block. Every time you draw a knife from the block, it passes through a built-in sharpening mechanism that maintains the edge without any separate tools, whetstones, or electric sharpeners. You just cook. The set includes 17 pieces, which covers every cutting task a home kitchen could need — from a large chef's knife down to a paring knife, plus steak knives, kitchen shears, and the block itself. The blades are made from German stainless steel, which is known for being tough, flexible, and resistant to rust — a practical advantage in humid environments where knives can corrode quickly if not dried properly. The black finish on both the block and the handles gives the set a clean, modern look that works on any counter. For a household that cooks daily and wants knives that stay sharp without any maintenance routine, the NeverDull system is a genuinely clever solution. Seventeen pieces is also generous enough that you will never find yourself reaching for a knife that is not there.
This is for the home cook who wants a complete, always-ready knife set without ever thinking about sharpening. The built-in block sharpener makes it ideal for busy households where knives get heavy daily use — chopping, slicing, and prepping from scratch — but nobody has time for a separate maintenance routine. It is not the right choice if you are a serious knife collector who prefers to sharpen by hand on a whetstone; the NeverDull system is built for convenience, not for enthusiasts who enjoy the ritual of sharpening.

How People Use the Ninja NeverDull 17-Piece Knife Block Set with Built-in Sharpener
Pull the chef's knife from the block, cook, wash, return it. The built-in sharpener does its job every single time. After months of daily use, the edge is still maintained — no whetstone sessions, no electric sharpener on the counter, no excuses for cooking with a dull blade.
With 17 pieces covering every blade type, you have the right knife for every task in one set. Chef's knife for the vegetables, bread knife for sourdough or artisan loaves, paring knife for the fruit, steak knives for the table. No improvising with the wrong blade.
The rust-resistant German stainless steel handles kitchen humidity better than cheaper stainless blades that spot and corrode. Wash, dry, and return to the block — the steel holds up without special treatment.
A 17-piece set with a built-in sharpener is a complete kitchen knife solution in one box. For a newly married couple or someone setting up their first home, this covers everything they need from day one — and the NeverDull system means the knives stay sharp for years without any extra purchases.

What Our Editors Found
Editorial observations based on hands-on research and testing notes from the Best Homes Finds team.
Never thought about sharpening again
I have been cooking daily for years and the built-in sharpener is the feature I did not know I needed. I just pull the knife out, cook, wash it, put it back. Three months in and every knife still cuts cleanly. The German steel handles kitchen humidity without any rust spots. Best knife set I have owned.
17 pieces covers everything
I was skeptical about needing 17 pieces but I use almost all of them. The chef's knife for daily prep, the bread knife for sourdough, the steak knives for the table. The black finish looks sharp on the counter and the German steel has not shown a single rust spot despite our humid kitchen. The built-in sharpener is a genuinely clever design.
Great system, takes up counter space
The NeverDull concept works exactly as advertised — the knives stay sharp without any effort on my part. My only note is that the full 17-piece block is large. Measure your counter space before ordering. If you have room for it, the set is excellent value for what you get.

Ninja NeverDull 17-Piece Knife Block Set with Built-in Sharpener — Common Questions Answered
How does the built-in sharpener in the block work?
The knife block has a sharpening mechanism built into each slot. Every time you pull a knife out or slide it back in, the blade passes through the sharpener and the edge is automatically maintained. There is nothing extra to do — no separate sharpening tool, no technique required. You just use the knives normally and they stay sharp.
Why German stainless steel specifically?
German stainless steel is known for being tough, flexible, and highly resistant to rust and corrosion. In kitchens where humidity is high and knives can corrode quickly if not dried immediately, rust-resistant steel is a practical advantage. German steel is also more forgiving than harder Japanese steel — it is less likely to chip if it hits a bone or a hard surface.
What is included in the 17 pieces?
The 17-piece count includes the full range of kitchen knives — chef, bread, utility, and paring knives — plus steak knives, kitchen shears, and the knife block itself with the built-in sharpener. It is a complete kitchen knife system rather than just a basic set.
Can the built-in sharpener sharpen other knives I already own?
The built-in sharpener is designed specifically for the Ninja NeverDull knives and their slot dimensions. It is not intended as a universal sharpener for other brands. For your existing knives, a separate pull-through sharpener or whetstone would be the right tool.
