I carry 2 rescue knives. My primary expected use is flat webbing cutting (seatbelts).<br><br>The one I have in each car is the Jack Emergency Knife for cutting seatbelts (search for item 16909). The other which I carry on my belt is the Benchmade Rescue Hook.<br><br>Both are designed to cut webbing with a bit more safety than a traditional blade. <br><br>About a month ago on I-405 outside of Kirkland WA, a family of 4 were driving on the freeway and were involved in an accident where their car caught fire. The husband was assisted out of the car with sever burns, but his wife and two babies burned to death. It was reported that people tried to assist but had no knife and could not remove the seatbelts from the flaming interior of the car. I always carry the Benchmade.<br><br>I also have but no longer carry the Spyderco Rescue. I recommend this serrated Sheepsfoot blade for cutting larger lines.
