How to Choose a Survival Knife: What No One Talks About

This isn’t just another article on how to choose a survival knife.

Most people focus too much on knives and their features, missing the function and possible scenarios.


Imagine a survival scenario and put things into context when choosing a survival knife.


The main variables to think about are:

Survival Approach (perspective and opinion on survival)

Gear (resources at hand)

Skill level (experience and training that you have)

Location  (climate, area, and vegetation)

Time frame (72hrs, regular use, or long term use)


Obviously we can’t plan if we’ll be in a survival situation, but we can guess based on probability.

There are multiple approaches to survival. Hikers, preppers, primitive skills enthusiasts, bushcrafters, and survivalists all have their different ideas on what a survival knife should do.

This is why there is no perfect survival knife. It all depends on your own circumstances.

It helps a lot to know how you currently use or plan to use your knife.

I divide survival knives into two main categories: big and small. There are other variables, but size matters.


How to choose a survival knife based on your Survival Approach


Do you want your survival knife to function as your only survival tool?

Meaning do you see a probable scenario where the only thing you have on you is a survival knife?

Survival knife as your only survival gear


Or could you see having other survival gear on you as well?

Would you use your survival knife regularly, or is it going to be stashed in a bug out bag?


A big survival knife can do everything, particularly if it’s the only thing you have in a survival situation. Obviously the downfall is that it won’t be ideal for every task.


If you generally go outdoors often and pack camping gear, cutting tools, fire starters, etc. you might find a small survival knife to be more useful and practical.

If your knife is part of an long term survival pack or a go-bag then you might want to consider a compact survival knife for portability.


How do you use a survival knife? What’s your skill level?


If you want your survival knife to excel at splitting wood, batoning, shelter building, digging, prying, and cutting through strong materials, then you should lean towards a bigger, heavier knife.

If you want your knife to excel at doing first aid tasks, wild food preparation, feather sticks, notching, skinning, and carving, then a smaller knife would be ideal.

It’s important to be honest and assess your skill level

Which survival knife for your location?

The next big thing when considering a survival knife is your environment, climate, and vegetation.

Do you live in an area that has subfreezing temperatures in winter? Because batoning, splitting and cutting wood might be a task that you want your knife to perform very well.

Do you live in a tropical rainforest, where you often need to cut through vegetation when bushwhacking? If you do then you might want a survival knife with a machete inspired shape.

If you live in an arid area with thin and sparse vegetation then your knife won’t need to be big and rugged; you can opt for a more comfortable, compact knife.


Pick a survival knife based on your Gear

Many people don’t think about what other gear they carry with their knife.

Now, I know about redundancy, but if I always carry a fire starter with me then I don’t need a survival knife that excels at making a friction fire.

If I’m going on a long wilderness excursion I will probably bring an axe, saw, and multi-tool as well.

In that case, I don’t need my survival knife for splitting wood, hammering, or batoning.

The survival knife can’t compete with an axe or a machete.

What size should a good survival knife be?

Big survival knife: 9 – 11 in (23 – 28 cm) Parang, kukri and ka-bar knives are outliers and measure around 13 in or more.

Small survival knife: 8 – 10 in (20 – 25 cm)

As you can see there’s not much difference in length between a small survival knife and a big survival knife, the difference is in the shape and weight.


Survival Knife: Steel Types

Don’t get to fixated on the types of steel.

To put it simply, knife blades are made of two main steel types: carbon steel and stainless steel. It’s a matter of personal choice. Carbon steel might cut better but need more maintenance than stainless steel.

Carbon steel: Harder steel, retains an edge better.

Stainless steel: More resistant to rust and chipping, but is slightly less sharp.


What to look for in a Survival knife?



More often than not people buy survival knives that are black or brown. Been there done that, that’s what knife manufacturers make and people buy.

Last year I lost my brown LMF II survival knife. I learned a few lessons from that.

One of them is having gear that really stands out if dropped on the ground. I still love having gear in natural colors, but small, critical items that are easy to get lost should be highly visible.


choose survival knife sheath


The sheath is as important as the knife, just because a bad sheath can be the cause of a lost knife.

A good sheath will keep the knife truly secure. You should be 100% confident that your knife won’t fall off if you move the sheath quickly or turn it upside down. Otherwise modify your sheath or buy another one.

You don’t want to lose your survival knife when you really need it


Lanyard hole

I tie bright marking tape to my knife so that if I ever drop it, I can find it even in deep snow.

Fixed blade or folding?

There is really no option, only fixed blade knives, or non-folding knives can be considered survival knives.

Folding knives are just not sturdy enough to be relied upon in a survival scenario.

Full tang

Full tang makes the knife much stronger, but small survival knives don’t necessarily need a full tang.

It is a given that you have to handle a small survival knife more carefully. You just shouldn’t abuse a small survival knife.

If you want to use your knife as you would a hatchet and maybe abuse it by prying and splitting hard wood, you absolutely need a full tang knife.

Pointed tip

Make sure the knife you choose has a sharp point that can be used for drilling and making notches.


survival knife flat spine

Flat Ground Spine

This is crucial. A sharp, flat spine like the one above allows you to use your knife as a ferro rod striker. But it’ also makes carving much more comfortable; I often use the spine as a thumb rest for added pressure and control.

survival knife non serrated

Serrated Edge or Not?

I prefer non serrated edges because they can be sharpened with a rock.

Serrated blades are very effective, but should be left for knives that will not be used regularly and are only expected to be used in a short term survival situation (if you’ll store it in a survival kit and won’t use it then go ahead and pick a serrated blade).

If you plan on using your knife long term, or for regular use, then buy a non-serrated survival knife for ease of sharpening.

Gerber LMF II

survival knife lmf II

I lost my LMF II survival knife; I really liked it. The serrations are very effective, but hard to sharpen. The sheath is bomb proof, and versatile. The handle material can be easily damaged if you use a stick to hit the spine while splitting wood. It is a beast, and it’s weight makes it good for batoning. I think the grey color stands out a little better than the brown or black.

Steel: 420HC Stainless

Bear Grylls Ultimate Pro Knife

I own an earlier version of the BG Ultimate Pro Knife. Even though Gerber’s Bear Grylls line of products is geared towards lower end gear. I found my knife to be dependable and effective.

Gerber StrongArm

choose survival knife gerber

Another Gerber product, the StrongArm survival knife is an improved , streamlined version of the LMF II (in my eyes). It’s mainly geared towards military users (the pommel or butt is sharp for example). This is a great knife that won’t break the bank.

Weight: 7.2 oz
Cost: $$
Length: 9.8″
Blade Length: 4.8″

Small Survival Knives

Great to have when you have other survival gear as well. They are more precise, and more likely to be at hand because of their compact size.

Morakniv Companion

survival knife I bough the Morakniv companion knife for my 180 days in the wild. It is a great budget survival knife when paired with an axe or saw. I’ve used it extensively for filleting, skinning, notching and carving, and I really like it. It’s light and compact. The sheath needs improvement, but I’ve added a piece of bike tube to hold the knife securely. The bright colored options are a big plus.

Weight w/ sheath: 4.1 oz (116 g)
Cost: $
Length: 8.6 in (21.8 cm)
Blade Length: 4.1 in (10.4 cm)

Specialized Survival Knives

Knives for specific environments

BKR-7 Kabar

choose survival knife bk-7

For me the BKR-7 is specialized because of its length; it’s also meant to be a combat utility knife. This knife would be suitable for environments where you expect to do lots of batoning, and use the knife as a hatchet or parang.

Weight: 12 oz
Cost: $$
Length: 12-7/8 in
Blade Length: 7 in
Steel: 1095 Cro-Van carbon steel

Condor Kukri

choose survival knife kukri

Cost: $$$
Length: 14-1/2 in
Blade Length: 10 in
Steel: 1075 high carbon steel

Who makes the best Survival knife?

    I use a knife called the bush craft woodsman by Ontario knife company. Made of 5160 spring steel. Great for all tasks it seems. Chopping, feather sticks, carving and battoning. Check it out. Also the only folding knife that can be considered as good as a fixed blade knife is make by cold steel knives. It is called the pocket bushman. Great knife.

    – Blade Steel: German 4116 Stainless Cryo Quenched

    Great series. I disagree that a folding knife is no use. I have a lambfoot pocket knife with a 3″ blade. It maintains a wicked sharp blade and is legal for walking about the streets (the UK has very strict laws, and you can get arrested for having a knife blade longer than 3″). One question: how would you take a knife onto a plane? It seems to me that if you’re lucky enough to survive a plane crash, you’re going to need survival equipment pretty quickly, but you can’t get knives through airport security.
