Described herein are devices and methods for removing caps from bottles and vials. The devices can include locking mechanisms, teeth for crimping caps, especially
metal caps, and balancing tips that balance out the force exerted when the locking mechanisms are closed. The methods can include placing the devices on a cap attached to a
bottle, pushing down so that the teeth of the devices surround the cap, locking the
locking mechanism such that the teeth indent the cap, and removing the devices along with the caps from the bottles or vials.
