The appeal of a knife set with a built-in sharpener is real: one purchase, one location, edges that stay functional without remembering to grab a separate tool. But not all built-in sharpeners are equal. Some are excellent. Some are afterthoughts that just fill a slot in the block. Knowing the difference matters when you're spending $40 to $400.
This guide covers the best knife sets that include a sharpener, from budget block sets under $50 to the Ninja Foodi NeverDull system that genuinely changes how knife maintenance works. I'll tell you what each sharpening system actually does and when it's worth paying more for a better one.

Individual Product Reviews
Ninja NeverDull 14-Piece Knife Block Set (B09BGSY58L)
The most innovative built-in sharpening system on this list: Ninja's NeverDull technology keeps every knife sharp with each use.
Standout features: - NeverDull Technology integrated directly into the storage block slots - Premium German stainless steel blades with full-tang construction - 14-piece set with ergonomic handles balanced for chef-approved comfort
Ninja's NeverDull system is different from standard built-in sharpeners. Standard systems use a fixed slot with carbide or ceramic elements that you pull knives through manually. NeverDull sharpens the knife as you remove it from the block. The sharpening element is in the slot itself, so every time you take out a knife, it gets a calibrated touch-up.
At $279.99 with 3,063 reviews at 4.8 stars, this is the premium block set option. The German stainless steel is solid. The full-tang construction means good balance. The NeverDull system means you never have to think about sharpening between meals.
The honest limitation of any built-in sharpener: convenience comes at the cost of some edge quality. A whetstone produces a better edge than any integrated system. But for home cooks who will never use a whetstone, NeverDull is dramatically better than nothing.
Pros: - NeverDull sharpens every time you remove a knife, not just when you remember - German stainless full-tang construction matches premium quality - 3,063 reviews confirm the technology works in real kitchens
Cons: - $280 is a premium for a block set - Integrated sharpening removes metal over time, knives will eventually need professional sharpening
Astercook 15-Piece Knife Block Set with Built-in Sharpener (B0C1YBPJ43)
The original Astercook block set: 1.4116 German steel, acacia wood block, and a functional built-in sharpener at $39.89.
Standout features: - 1.4116 German stainless steel, the specific grade disclosed - Built-in sharpener in acacia wood block for convenient edge maintenance - Dishwasher-safe construction with laser-pattern finish on blades
At $39.89 with 2,238 reviews at 4.8 stars, the Astercook is the best-value block set with a sharpener on this list. The 1.4116 steel specification is meaningful and honest. The acacia block looks warm and natural. The built-in sharpener is accessible anytime you're at the knife block.
The sharpener here is a pull-through mechanism. You insert the blade and pull toward you. It's quick and keeps edges functional between proper sharpening sessions. It removes more metal than a whetstone with each use, but for daily home cooking, that trade-off is reasonable.
Fifteen pieces covering all standard knife types plus steak knives and shears. This is the complete kitchen setup at an entry-level price.
Pros: - 1.4116 steel specification provides confidence in blade quality - Acacia block is aesthetically superior to plastic or cheap hardwood - Complete 15-piece lineup at $39.89
Cons: - Pull-through sharpener is a convenience feature, not a precision tool - Laser pattern on blades is decorative, not real Damascus
Ninja K32017 NeverDull 17-Piece Premium Knife System (B09B7R3SY7)
The most complete Ninja set: 17 pieces with the full NeverDull built-in sharpening technology.
Standout features: - NeverDull technology across all 17 slots - Premium German stainless steel with full-tang, wear-resistant handles - 17-piece coverage: chef, bread, carving, santoku, utility, paring, 8 steak knives, and shears
At $399.95 with 1,025 reviews at 4.8 stars, the Ninja 17-piece is the most complete NeverDull system. Adding three more pieces over the 14-piece version (including an additional steak knife and one more utility-category knife), this covers everything a household of regular cooks would need.
The NeverDull technology is the same across both Ninja sets. The 17-piece adds coverage. If you regularly cook for four or more people and the table needs steak knives for every place setting, the two extra steak knives justify the price jump.
For most households of two to four people, the 14-piece is sufficient. The 17-piece is for larger households or cooks who want every slot covered.
Pros: - Most complete NeverDull coverage available - 8 steak knives covers full dinner table settings - German stainless quality matched with the most innovative sharpening system
Cons: - $400 is a significant investment - Fewer reviews than the 14-piece for purchase confidence
Astercook 14-Piece Full-Tang Cream White (B0DYP3J5BW)
Full-tang construction with a built-in sharpener in a distinctive cream aesthetic.
Standout features: - Full-tang construction lab-verified to reduce fatigue by 30% vs. Partial-tang - Built-in sharpener in hardwood block for maintenance - Cream white aesthetic with high-carbon stainless steel blades
At $49.98 with 590 reviews at 4.8 stars, this is the Astercook option for buyers who prioritize build quality over price. The full-tang certification is genuine. The cream aesthetic looks premium and suits modern kitchens.
The built-in sharpener is the same pull-through mechanism as other Astercook sets. What differentiates this set is the knife construction quality. Full-tang knives have better balance and durability than partial-tang knives. Over years of use, the difference becomes noticeable.
Pros: - Lab-verified full-tang construction for long-term durability - Cream aesthetic is distinctive and premium-looking - Built-in sharpener included
Cons: - Pull-through sharpener is limited compared to Ninja NeverDull - Cream color shows staining more than darker options
Ninja K12007WHBN NeverDull 7-Piece Essential Prep System (B0C6YH63D7)
The entry-level Ninja NeverDull set: seven essential knives at $119.99.
Standout features: - NeverDull technology in every block slot, same as the premium sets - High-carbon stainless steel blades that are durable and rust-resistant - White block with 7-piece lineup: core prep knives
At $119.99 with 497 reviews at 4.8 stars, this is the right entry point into the Ninja NeverDull system for buyers who don't need 14-17 pieces. Seven knives cover the core kitchen tasks. The NeverDull technology is identical to the premium sets.
If you already have steak knives or rarely eat steak, the 7-piece saves $160 over the 14-piece while delivering the same sharpening innovation.
Pros: - Full NeverDull technology at the lowest Ninja price point - 7-piece lineup covers core kitchen needs - White block suits lighter kitchen aesthetics
Cons: - $120 for 7 knives is still premium pricing - No steak knives included
Emojoy 18-Piece White Knife Block Set with Built-in Sharpener (B0DZHL47FD)
The most complete traditional block set with a built-in sharpener: 18 pieces including a boning knife.
Standout features: - 18 pieces: 9 distinct knife types plus 6 steak knives, shear, and built-in sharpener - German stainless steel hand-sharpened to 16 degrees per side - White block with full-tang ABS handles with finger bolster
At $89.99 with 6,406 reviews at 4.7 stars, the Emojoy white set is the mid-range value leader. 18 pieces is the largest traditional block set count on this list. The inclusion of a boning knife is a meaningful addition that most block sets at this price omit.
The 16-degree hand-sharpened edge is sharp for a German stainless block set. The full-tang ABS handles with finger bolster provide safety and balance. The white block looks clean and modern.
The built-in sharpener is the standard pull-through mechanism, not NeverDull technology. For buyers who want the most knives at a mid-range price with a functional sharpener, this is the answer.
Pros: - 18 pieces is the most in any set on this list - Boning knife included, often omitted at this price - 6,406 reviews provide strong purchase confidence
Cons: - Built-in sharpener is pull-through, not Ninja NeverDull quality - ABS handle is functional but not premium-feeling
Astercook 15-Piece Black Block Set (B0BFQLRHTJ)
The second Astercook 15-piece option: acacia wood block with laser-pattern blades.
Standout features: - Dishwasher tested 999 times with exclusive patented anti-rust technology - Acacia wood block with built-in sharpener - Premium 1.4116 German stainless steel with laser-pattern finish
At $49.99 with 2,681 reviews at 4.7 stars, this version of the Astercook 15-piece has more reviews than the B0C1YBPJ43 version. The construction is comparable. The laser pattern on the blades resembles Damascus but is explicitly stated as decorative, which is honest.
The dishwasher testing is genuine. Astercook claims each knife has been tested 999 times in dishwasher cycles with their anti-rust technology. The acacia block is the same warm aesthetic as the other Astercook acacia sets.
Pros: - Highest review count of the Astercook sets - Honest about the laser pattern (not claiming real Damascus) - Proven anti-rust technology for dishwasher use
Cons: - Slightly more expensive than the comparable B0C1YBPJ43 version - Laser pattern is cosmetic only
Astercook 15-Piece Black Block Set (B0BW9239PC)
The most affordable complete Astercook set at $39.99 with Teflon anti-stick coating.
Standout features: - Teflon anti-stick, anti-rust, and anti-oxidant coating for dent-free blade performance - German 1.4116 stainless steel with ergonomic handles for all hand sizes - Built-in sharpener included for independent edge maintenance
At $39.99 with 2,401 reviews at 4.7 stars, this is the budget leader among the Astercook block sets. The Teflon coating is a genuine feature: it reduces friction during cutting, prevents oxidation, and makes the blades easier to clean. Combined with the built-in sharpener, this set is designed for low-maintenance kitchen use.
For buyers who want a functional complete knife set with a sharpener at the lowest possible price, this is the answer.
Pros: - Most affordable complete block set with sharpener on this list - Teflon coating reduces friction and prevents rust - 2,400 reviews confirm consistent quality
Cons: - Teflon coating is not permanent, degrades over time - Pull-through sharpener wears blades over extended use
Amorston 15-Piece Black Knife Block Set (B0CFXNZ26Z)
An alternative to Astercook with 1.4116 German steel and the same built-in sharpener design.
Standout features: - 1.4116 German stainless steel with black non-stick anti-rust coating - Built-in sharpener accessible with one hand - 15-piece lineup identical to comparable Astercook sets
At $39.99 with 1,612 reviews at 4.7 stars, the Amorston is positioned as an alternative to the Astercook sets with similar specifications. If the Astercook is out of stock or this is priced lower at the time you're shopping, the Amorston is a legitimate equivalent option.
The black coating, 1.4116 steel, and built-in block sharpener follow the same formula. There's no meaningful differentiation between this and the Astercook at the same price.
Pros: - 1.4116 German steel specification disclosed - Equivalent to Astercook at comparable pricing - One-handed sharpener access is convenient
Cons: - No meaningful differentiation from Astercook - Fewer reviews than the competing Astercook sets
BRODARK 15-Piece Knife Set Steel King (B0B974GRLY)
A premium block set with 15-degree edge angles, NSF certification, and double-layer full-tang construction.
Standout features: - 15-degree blade angles for sharper cuts than standard German-style knives - NSF food safety certified - Full-tang double-layer construction with crossed handle design for 2x durability
At $84.99 with 1,273 reviews at 4.7 stars, the BRODARK is the premium traditional block set on this list. The 15-degree edge angle is notably sharper than most German-style sets (typically 17-20 degrees), and the NSF certification for food safety is a legitimate quality indicator.
The company's claim of "45-degree natural grip" refers to the balance point design that makes the knife most comfortable at a 45-degree angle in hand. The crossed handle structure is claimed to provide 2x durability vs. Other premium knife handles.
At $84.99 with two built-in sharpeners in the block, the BRODARK offers more sharpening access than most sets. If edge maintenance is the priority, having two sharpener slots is a practical advantage.
Pros: - 15-degree edge is sharper than standard German-style knife sets - NSF food safety certified - Two built-in sharpeners in the block
Cons: - Claims about handle geometry are not independently verified - At $85, competing with German brand sets that have decades of track record
Buying Guide: Understanding Built-in Sharpeners
Pull-Through Sharpeners vs. NeverDull Technology
Most built-in sharpeners in knife blocks use a pull-through mechanism: fixed carbide or ceramic elements that remove metal from both sides of the blade when you pull it through. This produces a serviceable edge quickly. The downside is that carbide pull-through sharpeners remove more metal than necessary and produce an edge that's functional but not as refined as a whetstone or fine ceramic.
Ninja's NeverDull technology is fundamentally different. The sharpening element is in the storage slot itself, and it operates every time you retrieve the knife. The NeverDull system uses a calibrated abrasive that's gentler per touch than a dedicated pull-through while being more consistent because it works automatically.
What Built-in Sharpeners Can't Do
No built-in sharpener can restore a severely dull or chipped blade. For damage repair, you need a whetstone with a coarse grit (400 or below) or a professional sharpening service. Built-in sharpeners maintain functional edges between proper sharpenings. They don't replace professional sharpening.
How Often Should You Use the Built-in Sharpener?
For pull-through sharpeners, once a week during regular use is sufficient. More frequent use removes metal unnecessarily. For NeverDull technology, it happens automatically on every use, which is the system's advantage.
Steel Grade and Sharpener Compatibility
Higher-hardness steels (60+ HRC) should not be used with aggressive carbide pull-through sharpeners, as the stress can cause chipping. German stainless steel at 56-58 HRC works well with pull-through sharpeners. If you buy a knife set with Japanese high-hardness steel, use a ceramic honing rod instead of the built-in carbide sharpener.
Block Materials and Sharpener Placement
The best block sharpeners are accessible from the front of the block with a clear, ergonomic slot. Awkwardly placed sharpeners get ignored. Astercook and Emojoy place their sharpeners in accessible positions. The Ninja NeverDull eliminates this consideration entirely by integrating sharpening into the knife slots.
FAQ
Is the built-in sharpener in a knife block actually useful?
Yes, for most home cooks. A pull-through sharpener keeps edges functional between proper sharpenings. It's not as good as a whetstone, but it's infinitely better than doing nothing, which is what most people do without a dedicated sharpener.
How does Ninja NeverDull work compared to regular sharpeners?
NeverDull uses a calibrated abrasive in the storage slot that contacts the blade every time you remove a knife. It's gentler and more consistent than a manual pull-through because it operates automatically and applies the same pressure every time. The result is that knives stay sharp longer without any effort from the user.
Do I need to sharpen knives from a new set?
Most quality sets are sharp from the factory. You can use them immediately. After regular cooking, hone with a honing rod before each major cooking session and use the built-in sharpener weekly.
Can I use the built-in sharpener on Japanese knives with 60+ HRC steel?
Be careful. Carbide pull-through sharpeners apply significant force that can chip harder steels. For Japanese knives, use a ceramic honing rod or a whetstone instead. The Ninja NeverDull system is gentler and safer for harder steels.
How long do block sharpeners last before they need replacement?
Carbide elements in pull-through sharpeners typically last 3-5 years with weekly use before they stop cutting effectively. The sharpening element in NeverDull blocks lasts longer because each contact removes less material.
What's the difference between a knife set with sharpener and buying them separately?
A built-in sharpener is always at the point of knife storage, so you use it. A separate sharpener lives in a drawer and gets forgotten. Convenience drives actual maintenance. For most home cooks, the built-in solution produces better long-term knife care.
Conclusion
For most home cooks who want reliable knives and maintenance in one package, the Astercook 15-piece at $39.89 is the right choice. Quality 1.4116 steel, a built-in sharpener, and a strong review history at a price that's hard to beat.
If you're ready to invest in genuinely better sharpening technology, the Ninja NeverDull 14-piece at $279.99 changes knife maintenance from a task to an automatic process.
For the most complete traditional block set with the best mid-range sharpener, the Emojoy 18-piece at $89.99 offers 18 knives including a boning knife and a functional built-in sharpener.
