Our "Shark-Tooth" Shape
While the shape of Hands on Crayon is unconventional, it is the result of hundreds of hours of research and meetings with occupational therapists.
It is a commonly misled notion that big and thick crayons are best for a child's fine-motor development. Leading research in the field of occupational therapy suggests that the ability to develop a proper pencil (or crayon!) grip is largely dependent on strengthening the muscles in our fingers. These overlooked muscles, can be strengthened in children when they use a small writing utensil, such as breaking a crayon in half, or using a shortened pencil. It is these findings that explain the relatively short stature of our crayons.
As for the triangular nature of a Hands on Crayon, this is to promote the "dynamic tripod" grasp, in which the thumb, index and middle fingers are holding a writing utensil. The dynamic tripod is the gold standard of pencil grasps, and aims to provide as much comfort as possible.
