The Benefits of Cake Knives

Surely, a cake knife isn’t something that’s a necessity in every household, but it can make all the difference.

This is especially true if you’re someone who bakes cakes on a regular basis or if you’re just looking for the cake set to cut your wedding or birthday cake.

Here are the best advantages of a cake knife or a cake knife set in your drawer!

The cake pieces will look amazing

Cake is wonderful and you can make the perfect cuts if you use a proper knife. In one or two strokes, you’ll make a uniform slice that will amaze your guests.

You can also use it for prepping your cake sponges or cutting lasagnas.

The cuts are cleaner

Thanks to being thinner than some other knives, there’s much less drag with cake knives when you use them to cut into a cake.

Hence, you won’t need to use a lot of pressure, which increases the risk of crumbling the cake or messing up the icing.

With the tiny serrations and long blades, cake knives help you press into the cake with minimal human effort without having to use a sawing motion.

The blades are long

Cake knives are known for their long blades. This is to ease the slicing through 8, 9, or even 10-inch cakes across the center in one move.

This is particularly important if you want same-size cake pieces.

It’s very versatile

Cake knife is more than just a cake knife- you can use it with so many other foods, including pastry, baked pasta, bread, fruits, veggies, etc.

It’s awesome for creating the best pieces from delicate foods thanks to its thin and sharp surface.

Great for serving too

A lot of the products we presented are cake slicing sets, that is, you get a knife plus a serving spatula.

Indeed, this spatula is quite versatile; after cutting the pieces, you can easily transfer them into plates without worrying about smashing them.

And, they’re also versatile; you can use them with so many other foods when transferring them from tray to plate.

Which Factors Are The Most Important?


When choosing a cake knife, it’s vital that you choose quality materials. This ensures the knife’s longevity and optimal sharpness.

Therefore, opt for a blade made of strong stainless steel, preferably made as one piece.

And, choose a handle that’s sturdy and constructed from quality materials such as polyresin and food-safe plastic.


The handle of a cake knife has to be well designed to optimize the slicing and cutting process.

Ergonomic construction is important to offer you a good grip and comfort. And, it’s even better if you choose one that’s extra padded.

Ones from quality plastic or poly resin are a good choice.

Blade type

When trying to find the perfect cake knife for you, you’ll notice that the blade is either serrated or straight. The one you’ll choose depends on what you’ll be using the knife with the most.

The former ones are recommendable for tougher cakes and foods on the outside and softer on the inside, for example, a wedding cake with icing, and to cut by pressing down rather than sawing into it.

The latter, as you probably guessed, is a more suitable option for softer cakes and foods with a similar texture both on the inside and on the outside, for example, carrot cake.

Blade sharpness

A blade, no matter its type, has to be sharp to do its job, i.e. cutting and slicing.

So, make sure you choose one that’s highly sharp and with an optimized edge. Otherwise, you’ll end up with smashed desserts!

Blade size

Since cakes are often made bigger and for larger crowds, you’ll need a long blade to be able to cut slices in one easy motion.

Ones that have 12- to 14-inch blades are optimal.

How to Use A Cake Knife?

First, make sure you have hot water around-run the blade under it, and then wipe it using a clean towel between cuts.

If you don’t have a sink, you can dip it in a bowl of water. Avoid breathing onto the blade to polish or warm it. Warm water helps keep the frosting intact, rather than smearing it.

Then, if you have cake with frosting, press straight down into it, without any sawing. To have a steady grip, put your thumb and index finger on the sides of the blade itself, but avoid touching the sharp parts!

If you have a round cake, make the first cut across the center. Poking into the middle first and pulling toward the edge on the outside isn’t recommendable, yet it’s something most of us do.

Avoid touching the cake with your fingers-but use a serving spatula to transfer it onto plates.

When to Clean My Cake Knife?

Cleaning your knives is a must after every use. This prolongs their longevity and preserves their sharpness. But, only if you do it the right way!

Although most of the models we presented today are dishwasher-safe according to the manufacturer, sometimes, overuse of harsh chemicals can encourage dullness in the blade and stains.

To prevent this, it’s always better to clean your knife by hand. Use mild dish soap and warm water and dry it with a towel before storing it away.

Should I Sharpen it?

After a certain period, every knife out there tends to reduce its sharpness. This is why regular sharpening matters. You always have the option to take your knives to a professional if you’ll feel more comfortable like that.

If you want to give it a go at home, consider the blade’s type, i.e. serrated or straight. For the former, use a ceramic honing rod.

The rod’s shape is made to fit into the blade’s serrations. Always begin at the back end of the blade and put the rod into the serration.

Position it to match the angle of the cut in the serration. Then you slide the rod toward the blade’s edge which cuts. Repeat it for every serration. Several passes will be enough for each of them.

For straight-edge blades, you can use a whetstone-this sandpaper-like block is soaked in water before use.

When sharpening, you hold the knife at a 20-degree angle against it and gently pull each side of the knife against the stone. You repeat several times.

Whetstones usually have 2 sides, i.e. coarse vs. fine side. Begin with the rough side if you have a very dull blade.
