The Victorinox Classic SD—A True EDC

My true EDC knife is my 2-inch Victorinox Classic SD. There is rarely a day that goes by that I do not leave the house at least once. In order to leave my house, drive, and get back inside, I need my keys. Since this knife is so small and light, it stays on my keychain; therefore I carry this knife almost every single day.

Even if you have never owned one, you probably know someone that does. I have mine in the classic red color; however, they come in many other colors and patterns. There are even options that have Alox aluminum handles, for increased sexiness and durability; although this means you lose the tweezers and toothpick.

Here are the reasons I believe this is as close to perfect as you can get, in a keychain knife:

  • Tiny: The Classic SD is only 2 inches long, less than half an inch thick, and weighs in at less than an ounce.
  • Functional: Do not be fooled by its miniscule size. This little tool boasts 7 functions.
  • Well Made: This tool, as with all other Victorinox knives, comes with a lifetime warranty.
  • Iconic: Pretty much everyone everywhere recognizes this knife.

Individual Functions

There are two Classics: The Classic, and the Classic SD. The only difference is that the “SD” has a flat tipped screwdriver on the nail file; whereas the standard Classic does not. Today, we are talking about the Classic SD. As previously stated, this little tool contains 7 functions. All of which will get used more often than you think; should you decide to buy one for yourself. You know you want to…….

Knife Blade

The Classic SD’s blade is a very small version of the original Swiss Officer’s penknife blade, comes out of the box sharp enough to shred paper easily, and has the words “Victorinox – Swiss Made – Stainless” stamped into the base of the blade.


The scissors on the Classic SD are the same design as the full sized scissors found in other Victorinox SAKs; and work just as well. Some people will tell you that they are only good for shirt tags and loose threads; I can tell you, from personal experience, that they are just as good for fingernails, speaker wire, small paperclips, paracord, school projects, and those little box tops your kids are always bugging you about.

Nail File/2.5mm Screwdriver

The nail file works great for filing nails, but you already knew that. The screwdriver is the star here. It is a flat tipped screwdriver blade that is small enough to also work with most Phillip’s screws. This little feature also works well as a small pry bar/scraper; and, in an emergency situation, it works well as a tension wrench to assist in picking locks. (Don’t ask….)

Toothpick and Tweezers

The toothpick and tweezers come standard in all of the regular ABS/Cellidor models; however, the Alox version of the Classic SD does not have them. The toothpick works well as a toothpick; but, in a pinch, it also works well as a rake/pick for picking simple locks. (Stop right there. I already told you not to ask. Don’t make me tell you again.)


This one does sort of bug me, because I don’t really see this as a “tool”; but who am I to decide such things. The keyring works well for attaching the knife to your keys. There; I said it. Happy?


Overall I absolutely love this knife. Some may see it as a toy or a gimmick; but I can tell you that the Classic SD is no joke. It may be tiny, but it is ready for work, and will take a lot more abuse than you would think. As you can see from the pictures, mine is pretty beaten up from being on my keychain for about 3 years. My Classic has opened many boxes, blister packs, and a couple of locked drawers.

If you don’t have one, you should. (You could buy it on Amazon.) They are so lightweight you can just throw it on your keyring and forget about it, until you need it, and at approximately $12, what is there to lose?

What Does EDC Mean?

With the ever-increasing number of people that have become interested in prepping, or at least watching shows where other people talk about prepping, EDC has become a very widely used acronym. EDC stands for Every Day Carry, and is used to describe tools/weapons that you carry on your person every day. I have noticed that people have started throwing this term around very loosely.

You can look on the internet and see someone with 10 knives laid out in front of them, and they will still refer to them as their EDC. Obviously they are not carrying ALL of those knives, on their person, every day; unless they have many hidden pockets in those tacticool 5.11’s they just HAD to have ... because prepper bro.

Agreed on all counts. A high-value item for under $12 or so. Much more robust capabilities than are apparent at first glance.
