Do I need a straight or an angled palette knife?


An angled palette knife is a great addition to any cake artist’s toolkit - the angled blade helps to keep your hands and fingers away from the surface of the cake to prevent damage. 


However, a straight palette knife works just as well as smoothing out your icing or filling. You just have to be more careful not to touch the cake and smudge your design!

What size of palette knife do I need?

The size of the palette knife you need depends on what you are decorating. 

  • For adding frosting or filling to cake layers, anything from about a 5-inch to 8-inch palette knife will do the job.
  • For larger cake tiers, go for at least a 10-inch palette knife. This will allow you to work across a larger area, speeding up the process! We have palette knives up to 14 inches for your largest cakes.If you are using a palette knife to create smaller, more intricate shapes like flowers, a smaller palette knife is needed for extra control. 

What size of palette knife is best for cupcakes?

For decorating cupcakes, a smaller blade is best. A 3 or 4-inch palette knife is perfect for applying smaller amounts of frosting and smoothing it out easily. 

Why is my palette knife handle breaking?

If you are going to be regularly decorating using a palette knife, it is best to invest in a good quality brand. Cheaper palette knives tend to be flimsier, meaning the handle might break or the blade might be too flexible. 

A good quality investment from Ateco or PME is so worth it. They have solid grip handles which are comfortable to hold for long decorating sessions.
