That guy shiny thinks a squirt and opinel can do everything under any circumstances, I was just setting him straight lol
Dude... I don't mind disagreement. I can live with vigorous disagreement.
But I would ask that you not make up things and then claim I said them. I never said a Squirt and Opinel can "do everything under any circumstances". Really.... Please stop making stuff up like this. If you want to disagree with me, fine. Then be honest enough to disagree with what I've actually written instead of erecting a strawman that I didn't say.
Just so you can shoot at the right target, what I've said repeatedly is that one doesn't need any more knife for safe travel in the backcountry than a Squirt
or a Classic. I've repeatedly noted that my Opinel gets carried strictly as luxury item as I prefer it for food prep.
Can you describe a circumstance in which a fixed blade (or large folder) is truly
needed?
As you consider your answer, remember we're talking about ultra light camping. Fires and shelter building are not needed when carrying common backpacking/camping gear, including in the shoulder seasons and in the winter. This is demonstrated routinely every winter as thousands and thousands of people head into places where fires are either forbidden or impractical. They often face unplanned challenges and work around them relying stoves, tents/tarps and clothing. One can travel safely in the backcountry without a fixed blade (or large folder), even in winter. It happens all the time.
For the record, I almost always carry at least my Opinel as a luxury item because I simply enjoy having it with me and that alone is good enough reason to carry it. If people want to carry their Busse broad sword, it's no skin off my nose so long as I don't have to deal with ravaged woods and don't have to deal with a rescue of a worn out hiker who carried too much weight.
And for the record, I sometimes carry a fixed blade when I'm going on a trip where I plan on making fires because it's both legal and reasonable to do so. My wife and I went out a few weeks ago and took the dog and I took a fixed blade and folding saw to maintain a fire. Still burning off old dead fall left behind from a hurricane that left lots of junk along the rivers.
If a fixed blade makes you happy, carry it.
