There are several great advantages to using collapsible entry tools. Which one is best for you can only be decided by you to meet your specific needs.
One advantage is real estate. The smaller the forced entry tool, the easier it is to carry. With Bushido collapsible tools, it's easy to find a wearable pouch that will hold your tool set. Many back panels that attach directly to your plate carrier are perfect for these tools.
Increased leverage in a snap! Use the tactical entry tool in the collapsed state or open up all the way to get the maximum leverage needed to breach. This eliminates the All or None scenario of having a tool that is not long enough.
The last significant advantage is being able to dial in the exact length you need. Not all crack houses are created equally. The hallway may be too narrow for a full length tool. With these collapsible tools you can fix the length to any length needed, including just short enough to clear the wall opposite of your target door or window.
