This knife has stood the test of time, first purpose-made in WW2 for the US Marines and popular since in the civilian world. Manufacturer's short run-down here. Full history at Wikipedia.
This particular knife has almost no chance of being worn out, possibly I will never get more than a few hours of use out of it before I die, but I don't see the point of getting a knife "for emergencies" which might not be up to the "emergency" uses it may be put to.
