resetting the pointer in a MySQL database table

Hi, I have a table set-up so that every time you enter an item, a unique primary key is assigned to it (using auto-increment). However, I've deleted all data from the table but when I go to add an item the pointer is still set at the number of the last item I entered. Is there any way of resetting it? Thanks.
