At Defense Mechanisms, we’re focused on delivering equipment that meets the demands of those who rely on it most. Developed in collaboration with Joe Weyer of Alliance Police Training, our new Weyer Collapsible Breaching Tools are engineered for durability, efficiency, and reliability, without the inflated price tag. Built to serve professionals who require dependable tools in time-sensitive environments, this next-gen design sets a new benchmark for collapsible breaching tools.

Engineered for Durability

This updated design refines a proven platform with targeted enhancements to increase longevity and reliability in demanding use.

• Improved Corrosion Resistance

All shaft and head components are now machined from stainless steel, significantly reducing the risk of rust and corrosion. This leads to easier upkeep and greater confidence in all environments.

• Reinforced Striking Face

The head features a solid, continuous striking surface—removing the open cavity present in previous versions. This design refinement increases strength and durability throughout repeated impact.

• Integrated, One-Piece Construction

The shaft is press-fit into a blind hole in the head, pinned, welded, and blended into a single, seamless structure. The result is a tool designed to stay intact under heavy use, with no loose points or weak connections.

Thoughtful Design Enhancements

Beyond structural improvements, this generation of breaching tools incorporates key usability upgrades for safer, more intuitive handling:

Extended Shaft Length

• A slightly longer shaft offers better hand clearance, minimizing the risk of hand injuries when re-collapsing and stowing the tool.

Contoured End Cap

• The rounded end cap design allows for smoother insertion into our breaching tool holder, helping streamline deployment under time-sensitive conditions.

Simple, Reliable Operation

Whether you’re new to collapsible breaching tools or just need a quick refresher, here’s how the Weyer system works:

• Twist Collar Deployment: Loosen the collar, and let gravity do the work. The shaft extends smoothly, no springs or failure points — just simple, mechanical reliability.

Configuration Guide:

Configure the tool for the task at hand.

• Extended: For swinging or break-and-rake applications

• Collapsed: For ramming or compact storage

• Hybrid: Hammer collapsed, pry extended – ideal for setting leverage
  
  

The system is intuitive, fast, and built for those who rely on their tools to work—without exception.

Proven in the Hands of Professionals

Actively fielded by SWAT teams and patrol officers across the country—supporting felony warrant service, emergency wellness checks, and other critical entry operations—these tools are earning trust in active operations nationwide.

Professional-Grade Performance, Without the Premium Price

Most breaching tools on the market exceed $600 per piece. Our complete Weyer Collapsible Breaching Tool set is available for $800 MSRP—and agency and officer pricing brings that number down even further.

It’s a purpose-built tool that delivers on performance—without breaking the budget.

Built with intent. Trusted by professionals.
