8 Best Knives and Scissors Sharpeners of 2026

Effortless precision meets pro-level performance in the WELLPEAK 4-Stage Electric Sharpener, a standout for home chefs who demand consistent, repeatable results without the learning curve of manual systems. Its three-stage diamond abrasive system renews blades to a razor-like 20–22° edge, while the detachable ceramic hone rod delivers a polished, burr-free finish—ideal for both straight and serrated knives. The inclusion of a dedicated scissor-sharpening slot with diamond abrasives makes it one of the most versatile electric sharpeners on the market, solving the common frustration of dull shears and mismatched tools.

In real-world testing, the WELLPEAK excels at reviving heavily dulled chef’s knives in under a minute, with the coarse diamond stage quickly restoring the bevel and the fine stage refining the edge. The fixed 20° guide ensures angle consistency, eliminating guesswork, while the ceramic polishing rod brings a smooth, restaurant-grade finish that enhances cutting performance. However, the lack of adjustable angles limits flexibility for users with specialized Asian-style blades that prefer 15° edges. It handles stainless steel and high-carbon blades with ease but isn’t recommended for ceramic knives.

Compared to the Longzon and SHARPAL models, this sharpener delivers superior automation and edge refinement, making it a top pick over basic pull-through designs. While the ZWILLING Razor-Sharp offers solid performance for Japanese and Western blades, the WELLPEAK’s diamond abrasives and multi-stage process provide deeper restoration and finer polishing. It’s best suited for cooks who want set-and-forget sharpening with professional results, especially those maintaining a full knife set. For the investment, it outperforms manual and budget electric options in both edge quality and versatility.

Speed and customization define the 5-in-1 Electric Knife Sharpener, a high-performance tool built for users who want fast, tailored sharpening across diverse blade types. Its 100% diamond abrasives and 3-stage system cut through dull edges efficiently, while the 3 adjustable rotational speeds (LOW, MEDIUM, HIGH) let you match the aggressiveness to your blade’s condition—perfect for delicate sushi knives or rugged forged blades. The extendable angle clamp (20° to 32.5°) is a rare feature that adds serious versatility, making it ideal for those with mixed knife collections.

During testing, the HIGH speed setting revived a neglected chef’s knife in just 3 passes, with visible metal removal in the coarse stage and a refined edge after polishing. The removable chip absorber plate keeps the countertop clean—no messy metal dust—and the LCD display makes speed selection intuitive. It handles serrated knives and scissors well, though the scissor slot feels slightly narrower than the WELLPEAK’s. One limitation is the fixed coarse-to-fine progression, which doesn’t allow skipping stages for light maintenance. Still, it’s one of the fastest electric sharpeners in daily use.

When stacked against the Narcissus S867, this model offers greater control and adaptability, especially with its variable angles and speeds. While the WELLPEAK delivers a finer final polish, this sharpener shines in speed and customization, making it better for busy kitchens or users with varied blade types. It’s the go-to for those who value precision tuning over plug-and-play simplicity, and it justifies its mid-tier positioning with smart engineering and real-world efficiency.

Power meets stability in the Narcissus S867, an electric sharpener that delivers fast, reliable sharpening with minimal vibration—thanks to its 30-watt DC motor and low center of gravity. Designed for stainless steel, ceramic, and serrated blades, it uses dual diamond sharpening wheels to tackle both coarse reshaping and fine polishing in seconds. The ergonomic handle and anti-slip feet make it safe and comfortable to use, even during extended sessions, addressing the wobble issues common in budget electric models.

In practice, the Narcissus lives up to its quick-sharpening promise: dull knives regain a clean edge in 2–5 pulls, and ceramic blades respond well to the fine slot. The worldwide 100–240V compatibility makes it great for international users, and the dual sharpening system works reliably across straight and serrated edges. However, it lacks speed or angle adjustments, limiting customization for advanced users. It also doesn’t include a separate scissor sharpener—just a shared slot—so scissor results are functional but not exceptional.

Compared to the Longzon and SHARPAL manual models, the Narcissus offers superior speed and consistency, making it a better value than basic pull-through sharpeners despite its higher cost. While it doesn’t match the WELLPEAK’s polish or the 5-in-1’s adjustability, it outperforms in stability and motor durability. It’s ideal for users who want a no-fuss electric sharpener that handles daily maintenance with reliability. For diamond-powered performance at a mid-range price, it strikes a strong balance between cost and capability.

Affordability meets safety in the Longzon 4-in-1 Manual Sharpener, a budget-friendly solution that stands out by including a cut-resistant glove—a rare and valuable addition for nervous beginners. Its 4-stage manual system uses coarse and fine carbide notches followed by ceramic and scissor slots, delivering solid sharpening for steel and fruit knives without electricity. The non-slip base and compact design make it ideal for small kitchens or travel, solving the instability issue seen in cheaper handheld models.

In real use, the Longzon performs adequately for light to moderate dulling, with the carbide slots quickly setting an edge and the ceramic stage adding a decent polish. It’s intuitive: just pull the knife through each slot 3–5 times. However, achieving a consistent angle requires practice, and it struggles with heavily damaged or serrated blades. The included glove provides genuine peace of mind, especially for novice users, and the sleek design blends well on countertops. It’s not for precision enthusiasts, but it gets the job done for casual sharpening.

Compared to the AccuSharp and SHARPAL 191H, the Longzon offers better safety and broader stage progression, though it lacks suction or reversible blades. While the SHARPAL 104N provides superior angle control, this model wins on value and included accessories. It’s best for budget-conscious households or beginners who want a simple, safe starter sharpener. For the price, it delivers more than expected, especially when the glove is factored in—making it the smartest entry-level choice in the lineup.

Portability and durability redefine convenience with the AccuSharp system, a two-piece handheld duo that delivers professional sharpening anywhere—in the kitchen, garage, or outdoors. The diamond-honed tungsten carbide blades stay sharp for years, and their reversible design doubles lifespan, solving the throwaway problem of cheap sharpeners. The ergonomic handle with full-length guard ensures safety for both left- and right-handed users, making it one of the safest handheld options available.

In real-world tests, the AccuSharp restores a dull chef’s knife in under 10 seconds, with minimal effort and no power needed. The ShearSharp attachment works wonders on household scissors, hedge clippers, and even tin snips—unlike most kitchen-only models. It’s ideal for quick touch-ups, but not for rebuilding damaged edges or setting precise angles. The fixed 22° angle works for most Western knives but isn’t optimal for Asian-style blades. Still, its rugged build and dishwasher-safe design make it a long-term investment.

Compared to the SHARPAL 191H and Longzon, the AccuSharp offers superior durability and field readiness. While electric models like WELLPEAK deliver finer edges, this system wins for on-the-go reliability and longevity. It’s perfect for preppers, outdoor cooks, or anyone who wants a no-maintenance, always-ready sharpener. For sheer toughness and ease of use, it outlasts and outperforms most competitors—especially when you consider its 5–10 year lifespan between replacements.

Precision engineering meets versatility in the SHARPAL 104N, a pro-grade manual sharpener built for users who demand exact angles and repeatable results. Its dual preset angle system (15° for Asian, 20° for Western knives) eliminates guesswork, delivering razor-sharp edges tailored to blade type—a feature absent in most pull-through models. The coarse carbide and fine ceramic notches work in tandem to repair and refine edges, while the tungsten blade for scissors ensures fast, accurate sharpening.

In testing, the 104N excels at maintaining high-end knives, with the 15° slot perfectly suited for Santoku and Nakiri blades. The rubberized handle provides excellent grip, and the 5-stage process (including honing and scissor sharpening) covers nearly every need. It’s durable—rated for 10,000+ uses—and requires no power or setup. However, it’s not ideal for severely damaged blades that need aggressive reshaping, and the fixed angles limit flexibility for hybrid or custom grinds.

Compared to the ZWILLING Razor-Sharp, the SHARPAL 104N offers superior angle specificity and material quality, making it better for precision-focused users. While the WELLPEAK automates the process, this model gives greater control and portability. It’s the top choice for serious home chefs and knife enthusiasts who value accuracy and longevity. For angle-specific sharpening and pro-level results, it outperforms even higher-priced electric models in edge consistency.

Stability and simplicity converge in the SHARPAL 191H, a budget manual sharpener that punches above its price with a dual suction base twice as strong as standard models. This rock-solid grip eliminates slipping during use—solving a common pain point with handheld sharpeners—while the 3-stage system (carbide, ceramic, scissor) delivers reliable results for everyday kitchen blades. The tungsten carbide blades set a quick edge, and the ceramic notch adds a decent finish, making it a solid performer for routine maintenance.

In practice, the 191H is effortless to use: press the switch, attach to a flat surface, and pull the knife through. It works well on straight and serrated blades, though serrated results are less consistent. The compact size makes storage easy, and the no-hold design is a game-changer for left-handed users. However, it lacks angle guidance, so edge uniformity depends on user skill. It’s not for reviving battered blades but perfect for weekly touch-ups.

Against the Longzon, the 191H offers better stability and ease of use, though it lacks a glove. Compared to the AccuSharp, it’s less durable but more convenient for home use. It’s the best low-cost, hands-free option for average households. For reliable, no-fuss sharpening at the lowest price, it delivers where it counts—especially with its 3-year warranty and proven suction tech.

German engineering shines in the ZWILLING Razor-Sharp, a sleek, user-friendly sharpener designed specifically for Japanese and Western-style blades. Its dual ceramic grits (coarse and fine) per side ensure thorough sharpening and honing, while the fifth slot dedicated to scissors adds practical versatility. The non-slip rubberized base and safety grip keep hands clear of the blade path, addressing safety concerns common in pull-through designs.

In real use, the ZWILLING delivers a clean, consistent edge on both high-carbon and stainless steel knives, with the labeled slots making operation foolproof. It’s particularly effective on Zwilling and other German/Japanese brands, maintaining factory angles without over-grinding. However, the ceramic abrasives are less aggressive than diamond, so it’s better for maintenance than restoring battered blades. It also lacks speed or angle adjustments, limiting it to standard 15–20° edges.

Compared to the WELLPEAK, it’s less powerful but more precise for light sharpening. While the SHARPAL 104N offers better angle control, the ZWILLING wins for brand-specific optimization and safety design. It’s ideal for owners of premium knife sets who want a simple, reliable touch-up tool. For gentle, consistent honing that preserves blade life, it offers superior finesse over force.
