The Gerber Hinderer Serrated Edge Rescue Knife has a 3.5" sharp serrated blade that safely slices through seatbelts and it will cut through just about anything you'll encounter in the field. The knife also has a hook cutter, which lets you cut through clothing without cutting the person wearing it. Other convenient features include a window punch and an oxygen tank valve opener.
The knife includes large features and mechanisms so that it can be used while wearing turnout gloves without problems. The ergonomic handle keeps your hand comfortable while you work.
