A Detroit-area district says it's allowing Sikh students to wear a small, religious dagger to school, MyFoxDetroit.com reports.

The decision by the Plymouth-Canton Community Schools reverses a ban put in place in December after a fourth-grader at a Canton Township elementary school was found with a dull, 3- to 5-inch kirpan.

The kirpan represents a commitment to fight evil in the Sikh tradition. The dagger is a religious symbol that baptized Sikh males are expected to carry.

The principal initially let the boy keep the kirpan, but the school board instituted a ban because of parental concerns and conflicts with the district's rules against bringing weapons to school.

The Detroit Free Press and WXYZ-TV report that under the new guidelines, kirpans meeting certain criteria will be allowed for Sikh students.
