One of the big advantages of a victorinox is that they’re designed to be essentially maintenance free. As far as I can tell, the intention is that if you leave it in a bag, drawer, car, or just lose it under the couch for a decade, it will be ready to perform when you need it.

Another great benefit is that you can play around with different maintenance routines and find a system that works for you without worrying about corrosion or excessive wear. Try different oils, try it dry, see how it responds.

Clean it with water, compressed air, alcohol, or whatever else you feel like trying. Keep in mind that naturally derived oils will go rancid over time and if you’re too thick, it’ll go sticky.

A similar design philosophy is used with the blade, they are super easy to resharpen. It’s a great blade to learn how to repair and sharpen. It also doesn’t require oiling, but nothing is stopping you from trying it. Just stick to something food-grade so you can use it worry-free on meal prep if you have to.

Lastly, the most important thing you can do to prolong the life of your tool is to learn the limits of the tool set. No matter how well you generally maintain it, using it abusively once will break it.

You’ve got yourself a fine little knife, I hope it serves you well for years to come.

Clean the lint out of nooks and crannies every so often. That’s all I do, and I’ve had mine for a decade

I’ve had mine for about 35 years and done minimal maintenance. I’m about to send it to Victronox for a “spa visit” because the red casing got cracked. They will do a full cleaning and overhaul (and repair) on it for a very reasonable price. They really do stand behind their work.

Not much honestly. Keep it away from dirt and dust, so in a drawer, glove compartment etc. other than that oil the moving parts and only re-oil when it feels like it needs it. Keep it sharp too, including scissors and saw.

One last note, if it gets wet, dry it before closing.

I have one of those monsters with everything in it and my maintenance is wiping it off if it gets something on it. I think I might have put some WD-40 or bike chain oil on it one time. I might have sharpened the big blade once.

I have and use my father’s knife, and it really doesn’t need maintenance. He always carried it in his pocket, and I often carry it in mine. A few times a year, I’ll open all the implements, spray with detergent, scrub out dust and dirt with a toothbrush, and let it dry. That’s pretty much all it needs.

Sharpen the blades, clean out the pocket lint and maybe a bit of 3-in-1 oil when things are getting too gummed up.
I’ve had my knife for several decades. I did end up getting it replaced once under warranty early on. But, I blame my taking zero care of it and carrying it up sand dunes on a yearly basis. The sand really jammed up the blades.
I’m also going to replace the scales "soon"^TM. Said replacement having been planned as “soon” for the last few years. Ya, ya, I’ll get to it.

Buy a cheap one every few years, treat it like shit, recycle it when it’s dead.

It’s sad that it’s less work and less expense to re-buy an inferior product in many cases. Especially kitchen knives. Razor sharp $1 knives at the dollar store are much less expensive over a lifetime than one nice $100 knife (that can’t go in the dishwasher). Same goes for socket wrenches.

Ive got one but hardly gets any use as its illegal to carry in my country.
