Royal Icing Straight Edge Blade - 18"

Sharp edges can completely change the finish of a cake. Whether smoothing royal icing, refining buttercream or creating cleaner sides on larger celebration cakes, having a long straight edge gives decorators far more consistency across the final finish compared to shorter palette knives or uneven scraping tools.

This 18" Royal Icing Straight Edge Blade from PME is designed to help create smoother surfaces and more professional-looking finishes across taller cakes, extended tiers and larger decorating projects. The longer blade length makes it easier to level icing evenly in fewer passes, helping reduce drag marks, ridges and uneven texture during the smoothing process.

Particularly useful for royal icing work, the straight edge design helps achieve sharper sides and cleaner lines while offering decorators greater control when working across wider cake surfaces. It can also be used during buttercream preparation, chocolate work or ganache finishing where a flatter, more polished appearance is needed before decorating further.

Its slim profile allows decorators to glide more evenly around cakes while maintaining a straighter finish, making it a practical tool for both everyday cake decorating and more advanced celebration cake work.

Useful Tips:

For smoother results, hold the blade at a slight angle while rotating the cake turntable slowly and evenly. Using longer, lighter movements rather than short scraping motions can help minimise lines and overworked icing, particularly when smoothing royal icing or softer buttercream finishes.

Chilling buttercream or ganache slightly before using the straight edge can also help create cleaner sides and sharper edges during the final stages of decorating. Wiping the blade clean between passes helps maintain a smoother finish across the cake surface.
