OKAY... so I'll weigh in already! Geez... you write one opinion article, and everyone gets their panties in a twist. That's why I hardly ever come in here anymore. One of my readers pointed out that everyone's in a big argument over this, so I'll weigh in and hopefully dispel some of the silly misinformed commentary that's popped up.
First, I never said that a 4 or 6 inch knife had NO uses. I own a few small blades like this, but they are for very specific functions like skinning, gutting and picking junk from under my fingernails.
By the way, the guy who said you can't skin or gut with a larger blade... I beg to differ, and I'll stand behind my supposition that, "A big blade can do anything a little blade can, but the reverse is DEFINITELY not the case". I can whittle, notch, drill, skin, gut, shave tinder, and pick gunk from my fingernails with a large blade as well.
Now try being lost, and having to hack through a half mile of thick brush to get to a water source with a 4" pocket blade.
And to the guy who claimed that you do more notching and whittling to build a shelter than chopping... you're obviously spending a lot of time carefully fitting every limb in it's place?
More likely, you've never been hunting 10 miles from the nearest road, only to watch as a blizzard blew in. My first reaction is limbing the crap out of all the evergreen saplings I can find to lay down a thick, springy bed, followed by a lot of larger poles to frame up a shelter. I'm then laying a lot more LIVE... yes LIVE material on top of it.
I know the green crowd out there is horrified that I may harm some trees to save my own skin, and so be it. It's a simple fact... a big pile of dead wood and dry leaves is not something I'm going to build a fire in front of before I lay down to sleep! Yup... the LIVE stuff makes the shelter, the DEAD stuff is called "tinder" and "firewood", and you DON'T build your shelter out of it. Common sense rules!
Hacking the black "knots" out of the side of a birch tree for tinder is a lot easier if you have a real blade, as is lopping hunks of sapwood. I also want my blade to be big enough for effective digging, and to chop apart rotten logs to rustle up some grub... or grubs... yum.
I can make a fire drill just as effectively with my big blades... but I don't need to... I carry a Bic. No spark makers, no ploughs, no ice lenses, no boat matches, no fire drills, no 9V batteries and steel wool... I don't carry ANY of the stupid junk that the supposed survival gurus advocate. Why would someone carry a few matches when the same size and weight could be a lighter? Oooops... more common sense. Yet again, I seem to have brought the right tool for the job.
Trust me on this fact... go visit the USAF Survival School, and check out the dozens of instructors. These guys pretty much live in the mountains of Washington state, and you won't find a one of them with some little skinner. They also don't use the 5" Air Force survival knife they were issued. You'll find a large variety of blades, but they'll all have something in common. They're all 9-12" blades of heavy (1/4" +/-) steel. You won't see any of the "Rambo" style blades either... just big choppers. It's not about "macho", it's about common sense bringing the right tool for the job at hand.
Anyhow, this is my opinion, but it's based on 30 years experience using blades in actual wilderness settings (and yes... actual survival settings), not sitting in front of the computer trying to justify why I spent hundreds of dollars on a skinny little pocket blade.
Nuff Said?
