BrandNewCake Palette Knife/Glaze Knife Pierced 16cm The BrandNewCake Palette Knife/Glaze Knife Pierced 16cm has a size of 16 centimetres and a plastic handle. The knife is put through, meaning it has a kink. Because of the kink, you are much less likely to touch with your hand the pastry you are working on with the knife. Thanks to this knife, it becomes a lot easier to fill a cake and smear (mask) it tightly.
