How To Sharpen A Serrated Knife

This post may contain affiliate links. Read our full disclosure here.

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, 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 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.
