These knives are extremely light-weight and a bit sharper than the butter knives with flat cutting edges - great for small hands! They also don't have ridges, which is one of the most dangerous parts of table knives in my opinion.
The rubber handle and bottom of this bowl help it stay in place for young mixers. Mixing actually takes a lot of coordination, so having a tool like this to take some of the work out of it can be really helpful!
This bowl is pretty tall, so it's best used on a lower surface.
