Academy Director Travis Thomsen said parents and students were not notified of the incident.
“We didn’t feel like we needed to draw attention to it because it was a non-threatening situation,” he said.
Thomsen said the Ferrysburg charter school's policy for this type of situation is to contact police.
Spring Lake/Ferrysburg Police were called to the school shortly after 2:30 p.m. Tuesday after a teacher discovered the second-grader had the knife, Thomsen said.
“It wasn’t large enough to fall under state-mandated suspension and expulsion rules for dangerous weapons,” Thomsen said.
Those rules require the blade to be more than 3-inches long.
The knife the boy brought to school is a Cabela's multi-tool, with a blade less than 2-inches long, said Lori Spelde of the Spring Lake/Ferrysburg Police Department.
“It was not long enough for it to be considered a weapon,” she said.
