Best Knife Sharpeners (2026 Buying Guide)
A sharp knife is a safe knife. Here are the best knife sharpeners at CritPro for field use, home sharpening, and everyday carry.
A dull knife is more dangerous than a sharp one. It requires more force to cut, slips off surfaces unpredictably, and fatigues the hand faster during extended use. Keeping your knives sharp is one of the most important things you can do to get more performance and more safety out of every blade you own. The good news is that sharpening does not require expensive equipment or years of practice. The right sharpener makes maintaining a working edge fast, consistent, and straightforward.
CritPro carries knife sharpeners from Lansky, Sharpal, AccuSharp, Marbles, Schrade, Edgemaker, Arkansas, and EZE-LAP across every format and price point. Here are the best options right now.

What Is a Knife Sharpener?
A knife sharpener is any tool that removes metal from a blade edge to create or restore a sharp cutting angle. Different sharpeners use different abrasive materials including diamond, ceramic, carbide, and natural stone to achieve this. The sharpener you choose depends on how dull your knife is, what steel it is made from, and whether you are sharpening at home, at a workbench, or in the field.
Pull-through sharpeners are the fastest and easiest option for maintaining an edge on stainless steel knives with preset angles. Whetstones and diamond stones give you more control and work on harder steels but require more technique. Pocket and field sharpeners prioritize portability over precision and are designed for quick touch-ups on the go.
Sharpener Types Explained
- Pull-through sharpeners: Preset angle guides make sharpening fast and consistent. Best for kitchen knives, stainless EDC folders, and users who want quick results without technique
- Whetstones and diamond stones: Flat abrasive surfaces that require you to maintain the angle manually. Best for high carbon steel knives, serious sharpening enthusiasts, and anyone who wants the sharpest possible edge
- Ceramic rods: Smooth ceramic abrasive for honing and polishing an edge that is already reasonably sharp. Best for touch-ups between full sharpenings
- Pocket and field sharpeners: Compact multi-tool sharpeners designed for carry in a pack, pocket, or kit. Trade some precision for portability
- Cone and tapered sharpeners: Conical diamond or ceramic rods designed for serrated blades, fishhooks, and pointed tools that flat sharpeners cannot reach

Quick Comparison Table
Which Sharpener Is Right for Your Knife?
The right sharpener depends on the steel your knife is made from and how you use it. Standard stainless steels like 8Cr13MoV and 420HC sharpen quickly with any abrasive and are well suited to pull-through sharpeners and pocket tools. Higher performance steels like D2, S30V, and MagnaCut are harder and require diamond abrasive for efficient sharpening. High carbon steels like 1075HC and SK-5 sharpen easily on any stone and benefit from regular field touch-ups with a small pocket sharpener.
For field carry alongside a camp or bushcraft knife, the Marbles Double Sided Diamond or the Lansky Blademedic are the most practical options. For home maintenance of an EDC folder or kitchen knife collection, the Edgemaker M331B or AccuSharp bench mount will give you fast consistent results without technique. For the sharpest possible edge on a premium knife, the Sharpal 156N whetstone gives you full control over the sharpening process.
How to Choose the Right Knife Sharpener
