Survival knives, big vs small

One thing I have noticed here, is there is a massive following behind small fixed blades. There is all a notion that when it comes to a survival situation, you will only have one knife on you (lol). So it got me thinking, if I were to only have one blade on me, I think I'd rather have one of the larger variety.

One simple reason why, firecraft. While it is true that a small knife can do most things a larger one can do but it is missing the most ability that a large knife has: chopping.

Here is where I see the paths split and give a huge advantage to the larger knife. Sure you can baton chop into a smaller tree but notice that keyword. Smaller tree, a smaller tree=less wood, and less wood=getting wood more often for the fire. And that equals calories.

Sure small knives have their purpose but not in a one knife only survival situation. You probably think that small knives are great for prepping game, or carving/woodcraft. But keep in mind this is life and death, we would not be carving intricate handles on our spoons or whatever it is that you deem necessary. It may be a more tedious task with a large knife but it can be done with the same amount of calories.

Simply put, in a one knife survival situation I would want the largest knife that I was comfortable having with me everyday be it in a backpack, sheath, or wherever because in the end the best survival knife is the one you have with you.

To define a large/small I knife. I consider a small knife around 4 inches and a large knife around 7 inches.

I'm interested in knowing your thoughts.

If it's my choice I'd prefer about a 4.5" blade and a hatchet or axe. It's not feasible for me to EDC a large fixed blade so for day-to-day stuff I carry a 3.5" folder. I do keep a 6" blade in the car.
 
My 6" fixed blade is strapped to the Molle on the inside of my pack. My pack is always in the same building as me, and the building that I am in are all medium sized enterprises for the most part. Something where I could easily run and get it. Although if an earthquake struck and blocked my access I would be SOL. Hopefully the axis lock is tough enough for all possible duties in that situation. ;)
 
That's why I carry two blades piggybacked. Big one for chopping, small one for more intricate work, all in/on one sheath.
 
There is no answer to your question until you specify the survival conditions and the type of environment you're going to be in. Knives are tools, and different tools are needed for different situations.
 
Around here you pick wood off the ground and toss it on the fire. No need to chop or any of that. Use small sticks as chopsticks no need to carve. Pack a small tarp and cord for quick shelter. It's unlikely you'll get into a survival situation anyway.
 
A sturdy knife in the 4-5in range would be quite useful (ESEE 4, ESEE Laserstrike, Becker BK16, Becker BK10, etc), and is much more likely to be actually carried on your belt. As you said, they really lack in chopping. However, a baton can really help make up for that with some cross grain batoning if it is needed.

But I agree, if I knew I was going to be in a long term survival situation (somehow), and also was (somehow) restricted to only bringing one tool I think I would bring my Becker BK9. If I could bring another knife, it would either be my SAK Farmer, or my Mora carbon companion.
 
Due to my profession I cannot EDC a knife during work hours. However during my weekend warrior trips I'm a two knife guy. I will ALWAYS carry a small folder of around 3" clipped to the pocket and then a fixed blade of around 6" in the pack. Never will you find me without these two. However if your limiting me to a one knife only situation, I would feel ok with anything over a 4" fixed blade.
 
I'll weigh in. One knife-yeah right. Go big or don't make it home. BRK Brute/Kukhri/trailmaster. It'll be on my pack or waist. For me, I really can't tell the difference when I'm carrying in these two methods. With a big knife, I can do everything I can do with a little knife. However, the smaller knife can't take on the job of the larger knife without a great deal of effort.
 
as stated by the OP: "the largest one i'd be comfortable carrying" most times that's around the size of a 4-5" blade. assuming you're out in the woods already for this "survival situation" we find ourselves in, that's most likely the blade I will be carrying... as would most people after carrying various knives over the years find that a smaller knife does most things well enough and doesn't get in the way like a larger one. Imagine carrying your larger blade ...a KaBar for example versus something smaller like a fallkniven F1 or ESEE 4. believe it or not, that extra weight and length get in the way enough over time that most people will opt for the smaller one, unless their just a "I gotta have a big knife" kind of guy (compensating perhaps) but i'm not speculating on why. All i know is that i've carried the F1 on my excursions in the wild for over 7 years now and never felt like i've been lacking in the knife department, whether it's preparing game, shelter or fire, it's always done the job just fine. The OP's example of cutting down trees (large trees vs small trees) is a bit off IMHO due to the fact that day one in any reputable "survival course" the first lesson on firewood is to find what dry wood you can on the ground... so i don't see myself felling any redwoods any time soon. And in your spare time while you are waiting to be rescued or planning you're next move it is way easier to carve those decorative spoons with your smaller blade... hey, it fills the time.
 
All great points, and I cut down redwoods all the time when I get stranded in the woods. :rolleyes: I wasn't speaking from experience, because I have never been in a life or death survival situation, nor do I expect to ever be in one. I was speaking to the fact that many assume they will eventually find themselves in one and only have one knife. Just putting my thoughts on display.
 
It's all situational, just as with any other tool. I've more often found myself wishing I had a smaller knife than the other way around, but when those situations included fire preparation or other camp tasks, I also had a hatchet available that realistically was more capable than my large knife. Now, I absolutely always carry a small fixed blade knife (currently a Camillus Barbarian on a Tek-Lok mount) attached to a pack strap, where it is out of my way and adds minimal weight to a location that is already well supported. If I need a larger blade, it must have a sheath that likewise makes it easy to carry on my person. I'm not going to bother carrying a blade that has to be stuffed in a pack; if it's that big, it stays in my tent, truck, etc.
 
I personally don't keep my blade in my pack because of size, it is for the convenience of always having a knife that size with me in Seattle. Fixed blades are illegal within city limits but I wish to have it with me, so it is concealed in my bag.
 
For what its worth, I carry my BK9 on my hip (modded sheath though, so it rides much higher and takes up less space), and it doesn't bother me even after a few hours of wear. I think "generally" speaking, that the reason that many larger blades go in packs isn't so much the weight, as it is the sheath.
 
Small to med size blade in that unlikely scenario. I've been on multiple back country backpacking and minimalist trips. Sometimes with no tent and minimal food. . Never needed to baton or chop for shelter and fire.
It's fun, and I do it when family camping but in. Survival situation..... . Give me a BK16 and I'm a happy guy.
 
"a big knife can do what a small knife can do, but a small knife cannot do what a big knife can"

I agree, carry the biggest that circumstances allow. I normally carry a folder in the 3.5" range. I could carry a FB in my briefcase or in my car, but it would be limited to 5.5". I don't know what I would do with one if I carried it. One of these days maybe I will buy one to carry "just because".
 
Not sure what the experience of the OP is in the wild but personally I have found over decades of outdooring the best "one knife" situation for me has been a 5-7" quality leuku. They do it all.

The vast majority of tasks necessary in a SHTF scenario will be best and most efficiently accomplished with a "smaller" blade than a "big" blade.

I do carry a bolo or khukuri as a close supplementary second, but for a one knife scenario it's one of my leukus.
 
The flaw with "one knife only" scenarios is they are not realistic. Even for EDC, I have two blades. What you are asking for is a jack of all trades, master of none. For that purpose, a big blade is a good candidate, indeed.
 
I'll weigh in. One knife-yeah right. Go big or don't make it home. BRK Brute/Kukhri/trailmaster. It'll be on my pack or waist. For me, I really can't tell the difference when I'm carrying in these two methods. With a big knife, I can do everything I can do with a little knife. However, the smaller knife can't take on the job of the larger knife without a great deal of effort.

Spoken like a true weekend camper. :)
 
Large knives with very thick blades and obtuse edge geometry are great tools for making camp...ie chopping and drilling. I would not want to field dress a rabbit or deer or even worse try to fillet a catfish with a Becker BK9.

A Mora Companion has a thin, slightly flexible blade that cuts like a laser. Light camp chores, field dressing and food prep is cake with that knife.

If you follow the "one knife" philosophy then chances are good that I would end up know a survival situation with my Victorinox Farmer as that is the knife I most likely to have on me at any given time.

Long story short if I had to have one knife only, I'd want a 4" fixed blade knife of the Mora Variety.
