Present invention teaches a tobacco grinder with a guide shell and a grinder assembly consisting of an upper grinder part and a lower grinder part that is attached to a support shell. A material drawer is located on the side of the guide shell, slidably placed inside a slid slot, with a lock/release operation performed by a push release lock mechanism, making it easy for a user to operate. A curved well guides the ground tobacco down from the grinding chamber and funneled into the material drawer. The magnetized feature also makes the operation easy even if the grinder unit is help up-side-down.
