Maintaining And Using Your Swiss Army Knife

We all know that over time our SAKs suffer from wear and tear, and become harder to open and close.

Here’s a little tip from Victorinox on how to remedy that problem and keep your SAK working at optimum condition.

It’s recommended that you follow this process every 6-12 months depending on how often you use your knife.

Don’t open multiple blades at once

As you can see in the below picture, the spring is actually a solid piece of stainless steel that can be permanently bent by having more than one blade open at a time due to the way the blades apply pressure and bend the spring in various points. Even though Victorinox themselves dispute this we have heard many stories of people’s knives not functioning properly after opening too many blades at once.



  1. Do you know, that when you lose or break a part of an original Victorinox Swiss Army Knife, you can send it to the factory? And they replace the part (sometimes even the whole knife)for free. As long as you live. And usually even without a receipt.

    • That’s not true, though. The lifetime warranty only covers defects in materials and workmanship.

      “Victorinox AG … guarantees a life time against any defects in material and workmanship. Damage caused by normal wear and tear, misuse or abuse are not covered by this guarantee.”
