Abstract
“Modeling Play” is the important act which brings up the creativity of children. Out of various work tools for used to modeling, the utility knife has a high-risk of injury and the instruction of it is insufficient. The purpose of my study is the suggestion of utility knife for infants. An infant can be expected to be able to use the utility knife by an earlier stage, and acquire the method to use it properly. Moreover, the instructor will be able to instruct modeling comfortably.
