Abstract: A device constructed of a material strong enough to withstand the torque of a typical air wrench or breaker bar used by a lawn mower repair shop or a homeowner. The device must secure two lawn mower blades together in order to bind the blades. The device captures the opposing torque of both blades to cause a restriction in the blades ability to spin freely. To provide economics for manufacturing, one size should fit most blades and the device should require a limited quantity of materials and fabrication.
