There are a lot of knife companies who will tell you that you never will have to sharpen their knife. This is especially common for the serrated blades, where these companies claim you will always keep a sharp knife. Yet you will have to sharpen a serrated knife just as much as any knife type because blades simply will need to be sharpened.
Regardless of what they claim, the best knives that keep sharp for a long time are still not going to be out of the box sharp after long-term use. For outdoor knives and even everyday carry knives, it is incredibly common for these knives to remain pretty sharp. Yet they will slowly go from incredibly sharp to a little sharp. Meanwhile, those meant for kitchen use or for the dinner table will also need to be sharpened.
This is the most common place a serrated knife will be used, at least for the most part. It can be hard as well to keep a serrated blade sharp, which is why we have various products that can help with that. When to sharpen a serrated knife is often debated among serrated knife enthusiasts. The reasoning for this is often due to the type of thing you will be using it for.
As mentioned, they are common for the kitchen or dinner table. Yet the world of serrated knives is vast. For the outdoors, they are not as common as straight blades yet there are some knives with both serrated and straight blading. In these cases, the serrated portion will stay sharp longer than the straight blade. However, it may likely be able to cut easier in spite of not really being all that sharp.
The Good & Bad Problem About Sharpening A Serrated Knife
The idea behind a serrated blade is that you have a pointed sharp end consistently. Ideally, sharpening a serrated blade is seemingly unneeded because these points or teeth-like blades will remain useful whether they are incredibly sharp or not. That is the idea behind them and it is also why serrated blades are more popular for the dinner table and kitchen overall.
When you do not need to sharpen a knife a lot, it’s usually going to last longer. This is why even cheaply-made serrated knives will last in your home well past their expiration. They are still going to be able to cut stuff because that serrated blade is still going to be pointed and useful in a saw-like motion as you cut things with it.
Straight blades will eventually lose their sharpness and need to be sharpened after long-term use, with some expiring sooner than others. While this may not be commonplace to sharpen them consistently, you will eventually need to do so.
Therefore, it is true that serrated blades can last longer. Yet this does not mean you’re getting a quality serrated knife that will be better than a good straight blade. In fact, you’re likely going to be better off with the straight blade than a cheap serrated knife.
However, if you keep your serrated blades sharpened off and on, you will likely never have a problem with them and even cheap knives could remain for decades past their normal life.
The issue is that sharpening serrated blades can be quite difficult because, as their design shows, they are truly made for motion use where sharpness is not exactly key. Therefore, you are not sharpening them the same as regular blades. Mostly, because serrated blades were not meant for that.
Thus, you do not exactly need to sharpen a serrated knife for it to be useful. Yet when sharpened, they are lightyears better. It may be hard to find a sharpener that can do that, so we have compiled a list to help you out!

The Work Sharp Knife & Tool Sharpener is a tremendous tool to sharpen your blades with.

Another added benefit with this sharpener is the dovetail mount, which will help to ensure accuracy with your angle setting.

Chef’sChoice 15 Trizor XV EdgeSelect Professional Electric Knife Sharpener
Sharpens: All Kitchen Knives, Some Outdoor
While Chef'sChoice 15 might be for kitchen knives mostly, they can likely also work for some other knives too. However, we'd recommend sticking mostly to those you'd use in the kitchen only. This product happens to be capable of far more than we first assumed when we looked into it as well.
To convert 20-degree factory edges to high-performing Trizor XV 15-degree edges, this sharpener uses 100% diamond abrasives. This is likely why it is able to sharpen so well, as it's literally hard rock-like material.
Of course, this is an electric sharpener so it is bound to make SOME noise. Yet this is relatively low at just 65 to 75 dB. The automatic control that uses adjustable and flexible spring guides allows you to use the device in a way that works best for you.
The 3-Stage EdgeSelect sharpening system is versatile, offering the best possible sharpening for the knife you're using. Stages 1 and 2 are plated with 100% diamond abrasives that sharpen and hone edges while Stage 3 uses the flexible system to polish and prolong knife life. This includes our needed serrated knife sharpening skills.
The 15 Trizor XV uses strength and durability to offer a flawless, ultra-sharp 15-degree XV edge. This ensures you won't need to sharpen for a while and that each knife will be nearly factory new with each sharpening use. It seriously only takes a minute max for the first sharpening and then less than 10 seconds for those after.

Whetstone Knife Sharpener
Sharpens: All You're Capable Of
We are big fans of the Whetstone Knife Sharpener due to it being a manual sharpener. A lot of manuals can be hard for people to use but Whetstone kills that off very quick by offering you a guide on how to use their product along with the best ways to use it overall.
This product uses double-sided whetstone, along with a bamboo base for holding it. The overall sharpener uses 1000 Gritt that will sharpen blades regardless of their length or thickness while the 6000 Gritt within it will polish them. The double-sided aspect of this is tremendous and allows you to flip it over with ease.
They also added an angle support system to keep your knife in the right place to sharpen it. This can be useful for newbies to the manual sharpening game as well as veterans. The bamboo base is also useful in keeping things in place while you sharpen. This has an anti-slide rubber seal to keep things from moving. Bamboo is useful for sliding to be at a minimum but the rubber only goes to ensure this further.
While things like this are more for straight blades over serrated, this type of system can sharpen any knife. Meaning that what may be mostly for one type of knife is actually universal. Therefore, you can sharpen any serrated blade you have with it. This only makes it more valuable to us.
As mentioned earlier, this product could not be easier to use. You don't even need any special oils for it! All you need is water, as this wet stone is meant to help sharpen knives in a minimal way. We find this to be super user-friendly, making it perfect for a gift to moms and dads as well as a friend too!

That is very abnormal for a company to be so high on their product, so you know they are confident you'll love it.
