Big Fish Ligature/Seatbelt Knife

Ligature Cutter for Emergency Release

Ligature incidents, entrapment, and vehicle extractions require a cutting tool that can be used close to the patient or casualty. Control and hand placement matter when working in confined spaces or under restraint conditions.

The Big Fish Ligature Cutter is designed for cutting ligatures, seatbelts, ropes, and packaging during emergency response. The enclosed blade design allows cutting without exposing an open edge. This supports use near skin, clothing, or equipment.

A 9 mm mouth opening allows the cutter to engage thicker materials such as rope and netting while maintaining separation between the blade and fingers. The wider opening supports access to bulkier materials without increasing risk of stabbing or slashing injuries. The tool can also be used for controlled cutting of bags and packaging during deployment.

The Big Fish cutter is used across emergency services, custody settings, and specialist response teams. It is designed for repeated operational use where predictable handling and controlled cutting are required.
