What is the most efficient and widely used tool to open a jammed drawer?

The most efficient and widely used tool to open a jammed drawer is the power hydraulic tool. Power hydraulic tools are specifically designed to apply significant force to objects in a controlled manner, making it easier to free stuck mechanisms without causing excessive damage. They are often used in emergency situations where quick access is crucial, allowing firefighters to efficiently and safely open jammed structures.

In contrast, while a manual screwdriver can sometimes be used to manipulate the latch or screws, it may not provide the necessary leverage or force to open a drawer that is jammed tightly. An emergency pry bar can also be effective, but it requires skill to avoid damaging surrounding structures. A standard hammer may help in some cases, but using it incorrectly could lead to further jam or injury. Therefore, the power hydraulic tool stands out due to its effectiveness and capability to handle tough situations more seamlessly.
