Hi, my dad gifted my son (5 years old, we start them young in Alaska) a vintage Swiss Army knife with a fork and spoon. It is a bit rusty and I would love to return it to its former glory. I've done some Google searches with various answers, so I figured it would be best to ask some experts like you guys. Appreciate your help, thank you!
 
A photo would help...but gentle was in clean washing up water to start...a toothbrush and elbow grease...How vintage is it if its rusty?...
Cheers

Hi, and welcome!
I am not among those experts whose advice you are seeking, but someone hopefully will be along shortly to give you some tips. In the meantime, I have a few observations to share:
1) I too got my first knife at 5, and I still have most of my fingers, so I guess it worked out ok in the end. Still, for the first couple of years maybe supervise his use of the knife, and if you let him just have it he will almost certainly lose it.
2) You might try also asking in the Multitools subforum:

Here is a quick tutorial on posting images:
Here is how I post images. You do not need to be a paying member of BF or create an account with imgur for this to work:

How can I attach a pic? I only see where I can link from a website. Thanks!

Thank you and absolutely agree. He's defnitely being supervised. I also got him a little sheath that he hooks to a belt... which he wears even when wearing sweatpants so he can carry his knife haha!

That’s awesome :D:thumbsup:
Also, I just edited my post above with some instructions for posting images here. Seems to work for me using an iPad, anyway.
 
Victorinox or Wenger SAK?
If former you can send it in ... I think ...

Rust can be removed with steel wool, a bit of light oil (Mineral oil or 3 In One) and a little elbow grease. It may not be mirror polished (hence not a fingerprint or smudge magnet, and might not be usable as a signal mirror anymore, but will be rust free. 😁👍
After removing the rust, lube the joints and put a thin coat of oil on the blades and tools.

Most will tell you:"Use a food grade oil like mineral oil it there is even the slightest chance of using it for food prep or eating."
I don't bother For the last 62 years (since age 5), I just used what I had/have available: new or used motor oil, or transmission fluid, 3 In One, gun oil, WD-40, Olive Oil, Mineral Oil, used bacon grease from the grease pot on the stove ...
After wiping off the excess oil, there isn't enough left on the blade to matter. 😊 I've never gotten sick from using one of my knives to prep the food, or cut it to bite size at the table, no matter what I used to wipe down the blade.
I doubt I've consumed as much as 1 cc of non-food grade oils over the years from using my knife on my food.

Appreciate your response. Sounds like I need to make a trip to the hardware store! Not even sure where I'd find food-grade mineral oil here, so i'll take my chance too. :)
 
Sweet, thanks for your help. Here it is!
That thing is very cool, and I suspect quite old, though I know nothing about this type of knife. I’m just basing that off the shape of the smaller blade and the punch, the pins, and the bail. I really hope someone here can give you more info on it, and get you the restoration advice you need.

Tell your dad he’s awesome…
 
That looks like a Colonial or an Imperial? Except I don't know about the plated steel, and the fork and spoon make me think Japan.
Sorry, that wasn't the question, was it.
Yeah, I'm not an expert, but something about that knife looks American to me, not Swiss.

Steel wool and mineral oil, and a lot of elbow grease would probably be the way to go. Though, like afishhunter afishhunter I tend to just use whatever I have handy, which is usually Ballistol or Hoppes, both of which I've found good for cleaning old knives and guns.
 
Steel wool works for most of the blade, and a brass brush will work for the nail nicks, tang areas, and scissors. Definitely keep oil on it while you remove the rust, it will help!
That one should clean up nicely, lots of life left in those blades and tools:)

No doubt this is a vintage 'SAK', but just looking at the tool sets, there is a chance it is not directly made by Victorinox/Victoria/Elsener. Back when Victorinox started in 1890s and supplying to the military, they have contracted out their products to other makers in the region.

For example, you could find Hoffritz, Forges de Vallorbe L+C, D. Peres Solingen on a 'Victorinox' Soldier knife, but they would still be considered as part of SAK family and history. In fact, some of those off-brand could worth more due to their scarcity.

May I please get a photo of the stamp from the main blade, both front and back, if you are interested to learn more about this vintage knife? Another tip is to make a post on MTO under the SAK subforum, there are many friendly collectors and resident expert whom are willing to help identify this knife.

In terms of restoring, since this is a vintage model, I would probably keep it as is or go gentle on this. If you decide to clean and use it, I probably use Flitz to remove the rust and polish the tools. For the joints and dirt in the layers, I would put some dishwashing soap on and let it sit overnight on a counter. Then try to loosen or brush it off with a toothbrush under luke warm water in the morning. Afterwards, I would recommend lube up the tools and joints with mineral oil or Victorinox multi-tool oil(which has a higher viscosity)
