Apply the Coating

There are three ways you can apply the coating on a cake cutting knife. They are

  • First is by pouring coating material on top of the knife or applying it evenly. 
  • Second, by dipping inside the coating material.

Decide which method best suits you based on the coating material you are thinking of applying to the birthday cake knife.

Dipping or applying is best if you have a paste or solution of coating, such as melted chocolate, cream and sugar paste etc. Here you have to spread a thin layer of coating over the entire blade of the cake knife. 

On the other hand, use spraying if you have a coating material inside a spray bottle.

Similarly, if the coating material is solid, put that in a microwave-safe bowl and melt it using a microwave oven. And if you want, you can preheat your cake cutting knife for a while using a microwave oven; this will help spread the coating more evenly and smoothly.

There are many different substances that you can use to apply coating on your cake knife, and the best method depends on the ingredients you have available with you and the final look you are looking for.


What is the difference between an ordinary and cake knife?

A cake knife is a type of knife designed specifically for cutting cakes. Cake knives typically have serrated blades to help them cut through the soft, delicate structure of a cake.

They also have wider, more blunt blades than other knives, which helps prevent them from tearing or smashing the cake.

On the other hand, ordinary knives are not designed specifically for cutting cakes and may not have the same features that make cake knives ideal for the task. 

For example, ordinary knives may have sharper blades, which are perfect for cutting vegetables and fruits; and if you use them for cutting the cake, a knife can easily damage the cake layers.

What are common cake knife coating mistakes?

Not using a release agent: When you are coating your cake knife with fondant or chocolate, be sure to use a release agent such as vegetable oil or shortening; This will help prevent the coating from sticking to the knife and making a mess.

Applying the coating too thick: If you apply the coating too thick, it will be challenging to cut through the cake, and you will end up with a lot of wasted coating.

Not letting the coating set: Be sure to let the coating set before trying to cut the cake. Otherwise, the coating will slide right off the knife.

Why is a cake knife notched?

A cake knife is notched so that it can easily cut through cake. The notches help the knife to glide through the cake more easily, making it less likely to disturb the cake as you cut. This is especially important if you are cutting a cake that is already decorated, as you don’t want to ruin the decoration.

The notches on a cake knife also help to create even slices of cake. If you are cutting a round cake, the notches will help you to create even slices that are the same size. This is important if you are serving the cake to guests and you want everyone to get a fair share.

Overall, the notches on a cake knife serve two main purposes: to prevent squishing the cake, and to create even slices. These two factors make the cake knife an essential tool for anyone who loves to bake and decorate cakes.
