I have several Leatherman knives, all but the Mica are too heavy for backpacking. I did not know about the Leatherman Squirt and looked I up. REI says 1.9 ounces and $33. I know of a case where a friend had a fishhook in his finger and it would have put an end to a trip very early except some stranger happened to have a Leatherman with pliers so they could cut off the barb end and pull it back out.

I was surprised that several people don't carry much in the way of a fire starter. We often hike off trail in areas where we don't see anyone else. We obey the fire ban laws, well unless it is raining or has been raining and it is unlikely anyone will ever see us there.
