Police said another student told faculty members Monday morning that a student had a number of weapons in his vehicle.
Officers found a loaded .22-caliber handgun, two axes, a stun-gun, a razor blade knife, nine other knives, handcuffs and 200 rounds of ammunition.
The student is charged with possession of guns on school property.
Pickens school district spokesman John Eby says the student will be recommended for expulsion.
Eby says it appears the weapons were left in the car after being used for hunting and recreation. He says there is no indication the weapons were brought to school to harm anyone.
