Do Serrated Knives Need Sharpening?
Believe it or not, regardless of the type of knife, sharp knives are safer than dull knives. There is also the fact that sharp knives are more efficient to use. Do serrated knives need sharpening? Before we delve into that, we are going to find out what a serrated knife or blade is.
A serrated knife is a knife with a saw-like edge and it is used in a saw-like manner with the back and forth motion. They are excellent for cutting through belts and ropes, fabrics, and various other textured materials.
These types of blades also work perfectly on things that are soft, flexible or can be crushed easily with downward cutting. Good examples of materials that work well with serrated blades include bread, cooked meats, soft fruits and vegetables.
The downside to the serrated blades is that they can cause fraying when they cut things like ropes and fabrics and when the blade becomes dull, it becomes harder to sharpen, requiring special knife sharpeners or the services of professional knife sharpeners. A serrated blade does not cut as cleanly as an edge blade.
The other type of blade is the plain edge, which is a continuous smooth blade. They are the more traditional ones. They serve for a wider range of purposes than the serrated knives, cutting more cleanly. They are also easier to sharpen. This makes them the more popular blades amongst users.
Types of cutting: Do Serrated Knives Need Sharpening
In a bid to determine whether serrated knife blades can be sharpened, we are going to look at the different types of cutting. All these have different motions and require different types of blades.
This is when you use knife by applying force, forcing the edge in as you push the blade forward. A great example of this is cutting through a tomato. It works best with plain blades that are sharp and smooth and can easily tear through.
Slicing is using a knife in a sawing manner, pushing it back and forth and it is commonly used for breads and steaks. Serrated edges are the best choice for this since the serrations help bite into the surface.
Chopping involves cutting with a single directional, downward force. Gravity plays a major role here and the perfect example of this is chopping wood with an axe. It requires a plain polished edge with thickness and weight to cut without failing.
Having studied the different types of cutting, we can now deduce that whether you’re using a plain-edged blade or a serrated blade, in the long-run, it is bound to become blunt or even damaged. This would mean that all the blades would need to be sharpened, including the serrated blade.
Knife sharpeners for non-serrated blades are common e.g. stones, manual sharpeners or electric ones. When it comes to the serrated blades, it becomes a whole lot more complicated.
Electric knife sharpeners are the best choice for sharpening serrated blades and they need to have the feature for doing that. There are also manual knife sharpeners that can get the job done, but they are a lot more complicated. If one is not careful, they could end up damaging their blade.
All blades, whether plain or serrated, can be sharpened. The only difference is that it is easier to find knife sharpeners that sharpen plain blades. The ones that sharpen serrated blades cost more.
