Ask any martial arts expert and he’ll give you a different view on what you should look for in a knife. There is no consensus here because, like most things, you have to find what works for you, your body type, and your environment. Because of that, the following features are most important:

  • The knife must have a sharp, thin blade able to cut through materials such as thick leather.
  • The knife must fit securely in your hand.
  • The knife must be easily carried.
  • The knife must be legal. (Learn about the knife laws in your state).
  • The knife must be easily deployable.

Other features such as fixed or folding, serrated or flat edge, or stainless vs. carbon are individual preferences.

Background of the Spyderco Civilian

KnifeUp recommends the Spyderco Civilian as the best self-defense knife. Developed for undercover US law enforcement officers, the Spyderco Civilian has a curved S shape serrated blade that gives the user the ability to cut deeply into flesh. The curved handle allows the user to slash and stab without worrying about losing their grip on the knife. The thin blade tip gives the knife a great cutting tip that can easily cut through thick leather or jeans and the serrated part of the blade makes cutting through anything effortlessly.

Reviews of the Spyderco Civilian

Online self-defense experts stated that this knife is a great self-defense knife because of its intuitive design. Individuals without prior knife training can easily use this knife. No years of practice are needed. In addition to that, the ATS 55 steel will stay sharp for ages and, given that the blade’s shape limits the knife’s use to only self-defense, the knife will never become dull from day to day use.

Out of the 165+ reviews on Amazon, reviewers gave this knife 4.8 out of 5 stars. This makes the Spyderco Civilian one of the best self-defense knives on the market, hands down.

Other knives for self-defense on the market lack the design, durability, and power of the Civilian. What’s more, the knife’s folding blade mechanism allows for deep carry within your pocket, making the knife invisible from the outside.


If you are looking for the best knife for self-defense, check out the Spyderco Civilian. Spyderco is a US knife maker based out of Golden, Colorado and is known for making great, high-quality knives. Developed for undercover law enforcement officers, the Civilian is a great knife designed for only one thing: keeping you safe.

Hey Knife Up gang!  I'm Pete and I'm just a small man in a small rural town who loves the outdoors as much as the other million internet users that cruise sites like every day.  The difference is that I like to share what I know, and research what I don't totally know, so that YOU can have all the info you need to feel confident and prepared for all things outdoors related! And, for those who care, I have 42 years of wilderness canoeing and bushcraft experience in Northern Ontario and spend most of my Summers covered in mosquitos and fish slime, but hey, it's a lifestyle choice eh?

  1. Check Out Spyderco “other” line of blades: BYRD KNIVES. Look thru the Byrd Knife whole line up. After that, compare the prices. Tell me what you really think?

  2. I like the design of the spyderco, but Cold Steel’s new Talon II seem about the same design but with the Tri add lock, which makes this something I would watch out for when it comes out!

  3. Oh,, everyone gets cut in a knife fight. I carry a zero tolerance or strider right now,, but intend to use my kimber 45 should it come to that. Never posted before. Sorry I spoke too much.

  4. Actually, in my humble experience, of which I do have a small amount with over 20 plus years military and law enforcement experience. I have a limited “first hand” amount of experience. I find this knife blade to be excellent for defensive fighting. It would be great for cutting the tendons and muscles one needs to be able to use to hurt you, it would be great for cutting the places one needs to “bleed” someone out (the J cut for instance/femoral artery). Im no real expert. Just have witnessed enough to know this would work well. More ppl are killed with box cutters than any other blade,, but If I absolutely had to defend myself with a knife I think this would serve as well or better than many a straight bade, be they drop point or tango.

  5. Stabbing for self defense? Joe Spencer nailed it. This isn’t the movies and stabbing someone might kill them, but not very quickly. It takes time to bleed out, even from a vital organ, time you don’t have while someone is attacking you.

    In a self defense situation the point isn’t to kill them, the point is to end the threat as quickly as possible. Slashing the muscles, tendons, nerves,so they can no longer fight will end the fight quickly…and that is the point in a self defense situation, not to kill them.

    You want a slasher not a stabber for self defense, and there is no better slasher (i.e. self defense) knife on the market. Spyderco was dead on with this design.

  6. “*sigh* where do these reviews come from….this is not the best for self defense.”

    Spyderco disagrees with you. I’m going to go out on a limb and say they probably have moe experience then you.

  7. “Any true knife person will tell you that this knife is not good for self defense.Imagine trying to stab with it. A straight blade is a much better option.”

    ummm.. any “true” knife person wouldn’t go near someone with that thing. A straight blade will cut you, this will tear you open. It’s a defensive slashing weapon not a stabbing weapon.

    The defense part of self defense is important here. The curve allows you to slash and also manipulate your attackers arms and movements by hooking them if need be. It’s not meant to stab, it’s meant to disable an attacker from being able to stab you.

    Try stabbing someone with that thing thrashing around in front of you. Even if you try that claw will hook into you and disable you. It is designed to dig in and go deep as you pull, following the curves of the neck, torso, arms, etc. It wont be a quick slash like a straight blade, it will be a large deep circumferential cut around a large part of you…tearing of all your arteries, muscles, and tendons in whatever part it hooks. You will disable your attacker. No knife fighting skills needed. Thats the point. Stabbing only works if you can get a clean stab in. This works just by making contact with any part of the body.

    I will agree it is not the best offensive weapon, and that is not the mindset behind it, but it is an awesome defensive weapon.

    Personally I’m going to trust that the engineers who design knives for a living, and who designed a knife specifically for self defense, probably know more then a random guy on the internet that thinks stabbing for self defense is a good idea….that and curved blades have been throughout history some of the most effective knives for centuries…karambit cough cough.

  8. Actually Jared, if you are attempting to protect your life or that of your loved ones from deadly assault, delivering a “stab” to the assailant should never be your objective. Stabbing creates a small wound channel that, in most cases, is going to be relatively shallow. While this may ultimately lead to the attacker being disabled or even dead, it probably isn’t going to end a fight quickly.

    You’re much better off with a blade designed for ‘slashing’ which can quickly cut through muscle and tendon. Cutting an achilles tendon or slicing through the dominant arm triceps muscle will give you a much higher chance of ending an attack quickly than will inflicting a ‘straight-on’ stab wound of small dimension.

  9. The design is very cool. The price that you link bottom of the post is cheaper than Amazon.! I like it

    Thanks for the heads up

  10. Any true knife person will tell you that this knife is not good for self defense. Imagine trying to stab with it. A straight blade is a much better option.

  11. Being an avid ‘knife guy’ who has many different knives/swords and carries at all times while awake I can sympathize with those who carry EDC and believe in knives as a viable means of self defense. In many cases, especially against an unarmed assailant or an assailant who is armed with something other than a firearm, a knife does have advantage in some situations, but I still respect the wisdom in the saying, ” Don’t bring a knife to a gunfight”! I would certainly not feel safe facing down an assailant armed with a gun when I only have a knife to counter with? If one thinks this is a winnable scenario then I would say that said person has been watching too many Hollywood productions rather than living in the real world. The reality of a knife vs gun is that the knife loses in most instances, there are even video clips of actual incidents where this scenario has played out and thus far the ones I have seen as well as read about have the knife wielder losing almost every time! If I have no other alternative, then a knife is better than nothing, but otherwise I prefer a gun if possibly facing an armed assailant? My firearms which include a Glock 21SF and Sig P250 Compact in .45 ACP for concealed carry can attest to my opinion on this issue.

  12. *sigh* where do these reviews come from….this is not the best for self defense. However, if you are going too EDC this knife, seriously consider a piece of strong leather or para-cord looped thru hole on end of knife. Makes it safer from dropping during use, or having it taken from you. You should also seriously consider a Karambit knife. Watch some knife self defense videos, and practice. Honestly tho….a knife for self defense, especially in a street scenario, a knife is better than a gun. For many reasons.
