Seatbelt cutter

Seatbelt cutters are explicitly designed to slice through seatbelts, as the name suggests. They typically have a steel spine with a serrated edge at one end and a sharp cutting hook on the other end. To use your seatbelt cutter, you simply place it on the belt’s face between where it is being pulled from and retracts along the long axis of the belt. Then, you press down hard on the belt so that it starts slicing through it.

Seatbelt cutters can be handy tools, but they also have some drawbacks that you must consider before carrying one around every day. One drawback is their size; most models are relatively bulky if carried individually in your pocket. This means that it is best to carry them around in your car rather than on your person. However, this is not true for all the models. Some models are small in size and you can attach them to your keychain as well. Another drawback of these tools is you can only use them for seatbelts. A seat belt cutter will not offer other benefits such as a blade for self-defense or a screwdriver tip.


  • Efficient at slicing through seatbelts.
  • You can carry them in your car for emergencies.


  • Bulky to carry in pockets.
  • It can only cut seatbelts.


Pocket knives offer numerous benefits over other types of cutting tools and should be considered by everyone regardless of their need for a seatbelt cutter. For instance, you can use pocket knives to cut through things such as cables and ropes, making them perfect for outdoor uses where you might find yourself in survival situations. They’re also safer than many other cutting tools because the blade doesn’t retract straight into the handle as it does with most penknives or box cutters. This means that fingers are less likely to end up in the blade should you slip while using any of these tools.

The only drawback of a knife compared to a seatbelt cutter is that knives are less efficient at cutting through things at close quarters. Without the correct technique, you might need to use more force when using a knife to cut anything in a survival situation.


  • You can use them in numerous situations and not just for cutting seatbelts.
  • Less likely to cause personal injury during use.
  • Often safer than other tools due to blade design.


  • It may not be as efficient as a seatbelt cutter at cutting seatbelts.
