I’d recommend Presto 08810 for any newbie in either cooking or outdoor activities, including hunting. It’s got your back whenever you need it.
Presto 08810 is remarkable in terms of the variety of knife types that it sharpens. It works with almost all types; including but not limited to, sports knives, hunting knives, and of course cooking knives.

#3. Chef’s Choice 290 Angle Select Hybrid Diamond Hone Knife Sharpener
Chef’s Choice has excelled in the industry since 1985, perfecting model after model. Its 290 AngleSelect Hybrid Knife Sharpener is no different. It’s one of the few hybrid models that caught my attention.
I think the 290 AngleSelect Hybrid is better suited for those who don’t mind a little manual work. Some people, perhaps more on the purist side, believe manual sharpening is better. In this case, we see the best of both worlds brought together in one knife sharpener.
For starters, it has three sharpening stages. The first two stages work automatically for your convenience, while the third stage is manual. The manual stage provides more of the polish while the first two do more of the intense sharpening.
The three stages are made of 100% diamond abrasives, which perfectly sharpen kitchen and outdoor knives with minimal scraping. The end result is sharp, durable, and burr-free.
It’s also adaptable, working equally well with Japanese and western knives. This is owing to its ability to switch between 15-degree and 20-degree angles.
While the AngleSelect Hybrid is easy to use, it’s not particularly easy on the eyes. It’s large and quite bulky.
Things We Liked
- Three sharpening stages and a final polishing stage
- Made of 100% diamond abrasives
- Burr-free sharpening
- Versatile and adaptable
- 1-year warranty
Things We Didn’t Like
- Large and Bulky
- Requires more effort than non-hybrid models

Things to Consider Before Buying an Electric Knife Sharpener
Knowing what to look for in an electric knife sharpener can be challenging. There are many factors that come into play. Here are some of them.
Safety
Safety always comes first. Always look for knife sharpeners with a guard to protect your hand and fingers from being cut. In terms of safety, the sharper the knife, the less force used. This results in far fewer injury rates. It’s also important in preventing carpal tunnel syndrome and repetitive hand injury.
Secure the electric knife sharpener on a stable, flat surface to prevent it from tipping over during use, and always keep away from children and pets. Use caution when handling the knife and the sharpener. The blade and the sharpening mechanism can be sharp and may cause cuts if handled improperly. Where safety gloves and glasses if recommended by the manufacturer.
Compatibility
You’d want to buy a sharpener that works with all kinds of knives; serrated or straight. Serrated knives in particular have special needs when it comes to sharpening.
Many electric knife sharpeners are not designed to sharpen serrated knives. Check the manufacturer’s instructions to see if the sharpener is suitable for use with serrated knives. If the electric knife sharpener is designed for use with serrated knives, follow the manufacturer’s instructions for the specific sharpening process. This may involve using a different slot or stage than the ones used for straight-edged knives.
Be aware that serrated knives can be more difficult to sharpen than straight-edged knives. It may take more time and effort to achieve a satisfactory level of sharpness. If you are not comfortable sharpening a serrated knife, consider taking it to a professional sharpener. They will have the necessary tools and skills to sharpen the knife safely and effectively.
There are plenty of different types of knives, all with unique features. Figure out which ones you use the most and the compatibility of each with your sharpener before purchase.
The edge angle and the blade style are also worthy of notice. If you’re just starting out with knife sharpening, you should familiarize yourself with different edge angles and what may work best for your situation. However, keep in mind the most common edge angle is 15-20 degrees, which will work great in most situations.
Slots and Stages
The keyword here is multiple. Look for an electric knife sharpener with multiple slots and multiple stages. Multiple slots allow you to remove burrs, while multiple stages allow you to perfect sharpening and increase the lifespan of your knives.
Knive Sharpening Material
There are many types of stones that can be used for sharpening knives, and the best type for a given knife will depend on the material of the blade and the desired level of sharpness. Here are a few common types of sharpening stones:
-
Natural stones: These are made from natural minerals and are generally more expensive than man-made stones. Examples include Arkansas stones, which are made from novaculite, and Japanese water stones, which are made from various types of natural stones.
-
Synthetic stones: These are man-made and are typically less expensive than natural stones. Examples include diamond stones, which are made from a matrix of diamond particles, and ceramic stones, which are made from a hardened ceramic material.
-
Oil stones: These are made from a soft, porous material, such as aluminum oxide, and are lubricated with oil during use. They are commonly used for general sharpening and maintaining the edge of a knife.
-
Water stones: These are made from a softer material, such as aluminum oxide, and are lubricated with water during use. They are commonly used for fine sharpening and can produce a very sharp edge on a knife.
-
Honing rods: These are thin, rod-shaped stones that are used for maintaining the edge of a knife rather than sharpening it. They are commonly made of steel, ceramic, or diamond.
It is important to choose a sharpening stone that is appropriate for the type of knife you are sharpening and the level of sharpness you wish to achieve.
