Different Types of Knife Sharpeners

Different Types of Knife Sharpeners are designed to keep your blades sharp, safe, and efficient — and yes, each type works differently depending on your skill level and knife collection. From traditional whetstones to modern Rolling Knife Sharpeners, choosing the right tool can make all the difference in performance and long-term knife care.

In this ChopChop USA guide, you’ll learn exactly how each sharpener works, the pros and cons of every option, and which sharpening method is best suited for home cooks and professionals. By the end, you’ll know precisely which type of knife sharpener fits your needs, cooking style, and sharpening experience.

What Does a Knife Sharpener Actually Do?

Before comparing the different types of knife sharpeners, it’s important to understand what sharpening really means.

A knife sharpener removes a thin layer of metal from the blade to recreate a clean, precise cutting edge. Over time, daily slicing causes the edge to roll, bend, or flatten. Sharpening rebuilds that edge by grinding fresh steel at a consistent angle.

Key Terms You’ll See Across All Types of Knife Sharpeners:

1. Sharpening

Removes metal to create a new edge.
Tools: whetstones, electric sharpeners, rolling sharpeners, pull-through sharpeners.

2. Honing

Realigns the existing edge without removing metal.
Tool: honing rod (steel or ceramic).

3. Polishing

Refines the edge after sharpening for ultra-smooth cuts.
Often done with fine-grit stones or ceramic rods.

Understanding this makes it easier to choose the right tool, because not all sharpeners do the same job.

Different Types of Knife Sharpeners

Below are the main categories every cook should know.

1. Whetstones (Sharpening Stones)

Whetstones are the most traditional and precise method among types of knife sharpeners. They range from coarse (200–600 grit) for damaged edges to ultra-fine (3000–8000+ grit) for sharpening and polishing.

How Whetstones Work

You hold the knife at a consistent angle (usually 15° or 20°) and manually slide it across the stone in controlled strokes. With practice, this produces extremely sharp, professional-quality edges.

Pros

• Most precise sharpening results

• Works for all knives, including high-end Japanese blades

• Can repair damaged or chipped edges

• Extremely long-lasting when maintained properly

Cons

• Requires skill, patience, and practice

• Time-consuming

• Must be soaked or lubricated depending on the type

• Beginners may scratch or unevenly sharpen knives

Best for

Chefs, knife enthusiasts, and anyone who wants maximal sharpness and total control.

2. Electric Knife Sharpeners

Electric sharpeners are one of the fastest types of knife sharpeners, using motorized abrasive wheels to grind knives at preset angles. You simply insert the blade into the slot, pull it through, and let the machine do the work.

Pros

• Fastest sharpening method

• Perfect for busy home cooks

• Consistent sharpening angles

• Easy for beginners

Cons

• Removes a lot of metal, shortening knife life

• Not ideal for thin Japanese blades

• Loud and less precise than whetstones

• Bulky and harder to store

Best for

People who want fast results with minimal effort and who mostly use Western-style knives.

3. Manual Pull-Through Knife Sharpeners

Compact and easy to use, these are among the simplest types of knife sharpeners. Abrasive rods are fixed at an angle — just pull your knife through the slot. Each slot contains abrasive rods set at fixed angles. You place the knife in the slot and pull it toward you.

Pros

• Extremely easy to use

• Compact and budget-friendly

• Works well for basic kitchen knives

• Great entry-level sharpening tool

Cons

• Less precise than stones or rolling sharpeners

• Can scratch the blade sides

• Limited angle flexibility

• Not recommended for high-quality knives

Best for

Casual home cooks needing quick, no-skill sharpening for everyday knives.

4. Rolling Knife Sharpeners (New-Generation Technology)

Among modern types of knife sharpeners, rolling sharpeners have surged in popularity for their simplicity, safety, and accuracy. A rotating diamond or ceramic wheel maintains a fixed angle (15° or 20°) as it rolls along the blade.

How Rolling Knife Sharpeners Work

You place the knife on a base or guide and roll the wheel along the blade several times. The wheel’s diamond or ceramic abrasives gently remove metal to create a clean, even edge.

Pros

• Extremely beginner-friendly

• Delivers consistent, repeatable results

• Safe and stable

• Compact and easy to store

• Suitable for both Western and Japanese knives (depending on angle)

Cons

• Not ideal for heavily damaged blades

• Cheaper models may have low-quality wheels

• Some limitations with large cleavers or thick survival knives

Best for

Home cooks who want a simple, clean, and accurate method without needing sharpening skills.

5. Honing Rods (Sharpening Steels)

Despite the name “sharpening steel,” these tools do not sharpen the blade. They realign the knife edge, which keeps knives performing well between sharpening sessions.

Types of Honing Rods

• Steel honing rods – tough, durable, best for Western knives

• Ceramic rods – smoother, provide mild sharpening

• Diamond rods – aggressive, remove more material

Pros

• Quick and easy

• Maintains sharpness longer

• Extends time between sharpenings

Cons

• Does NOT fix dull knives

• Requires correct technique

• Some rods can be too abrasive for delicate knives

Best for

Anyone who wants to maintain knife edges regularly.

6. Specialty Sharpeners

These tools are designed for specific applications and unique blade shapes.

Examples:

• Serrated knife sharpeners (individual tooth sharpening)

• Scissor sharpeners

• Outdoor field sharpeners

• Multitool sharpeners (compact and portable)

These aren't everyday kitchen tools, but they serve important niche purposes.

How to Choose the Right Knife Sharpener

Choosing among the different types of knife sharpeners depends on several factors.

1. Your Skill Level

• Total beginners → Rolling knife sharpeners or manual sharpeners

• Intermediate → electric sharpeners

• Advanced users → whetstones

2. Your Knife Collection

• Japanese Kiritsuke Knife → whetstones or rolling sharpeners

• Chef’s knives and Western knives → most sharpeners work

• Serrated knives → specialty sharpeners only

3. How Often You Cook

• Daily → regular honing + monthly sharpening

• Occasionally → sharpen once every few months

4. Safety & Convenience

If you want something clean, fast, and safe → Rolling Knife Sharpener.

5. Your Budget

• Budget-friendly: pull-through sharpeners

• Mid-range: rolling sharpeners

• High-end: premium whetstones or electric machines
