If you blend things that are less liquid, the blender sucks air down to the blades and you constantly have to shake the blender or push the food down to the knives with a spoon.
If you do it while blending, the blender might take a "bite" of the spoon.
There is a solution for this. A spoon that cannot reach all the way down to the blades. The "AnyShape Safety Spoon" stops just before it reaches the blades in the blender.
The spoon is made from Soft Shape, because it has been approved to be in contact with food.
