Me and Adam made a pencil grip that is curved to be comortable. These grip exist but none look like ours. It is a useful item because some people have a writer's callus which is a bump on your finger when you write the the writing utensil pressing onto your finger which seems to be rare. Me and my grandma have this special bump and most of the the other pencil grips we have tried have worn down quickly and we repeatedly had to buy more.
