My dad is giving me 3 knives he got in Iceland while in the Navy many many years ago. From the pics below you can see they're rusty so I'm looking for some good info on what the best method is to recondition them / remove the rust. Any tips/suggestions would be greatly appreciated.



Also, he's giving me a bayonet that his dad gave him (at top in picture). He said he thinks its from WWI or WWII, but is not realky sure. Is there anything I can look for to determine that?

TIA.

Those are some cool parangs. As for the bayonet. Is that the sheath it came with?

I had no clue those were called 'parangs'.

Yes, pretty sure that's the sheath it came with.

I would think that anything you do to them might make them flash rust if it was harsh. Might try calling a custom knife maker. They'll probably know what is the best thing to do on those specific types of steels

Looking at the sheath and the handle of the bayonet. It's WWII or newer for sure.

It's a different kind of steel than normal knives?

There are probably 20 different types of steels being used on knives at the moment. Each one with different properties

Are these old and possibly valuable ? If so, you could ruin the value by cleaning them.

Reconditioning them will destroy whatever value they have as collectable knives. You would be better off properly preserving them in their current state.

I think he was mainly trying to stop the rust growth, and make those spots look better. I don't think that is possible without some "overspray" that would effect the surrounding steel.

Maybe putting them somewhere with a bunch of desiccant packets

Mother's Mag polish and terri cloth, maybe a dremel to get them really shiny.

This is correct.

Just trying to get rid of rust really, but not sure I want to do anything to them if it'll ruin value.

Someone mentioned to me using a little baking soda and old tooth brush?

There are many chemicals that specifically attack rust and separate the iron and oxygen and transform them into a more stable compound. No idea how they do it, and have only seen them work on whole pieces of metal, not specific sections.

Once you find out what steel, call the manufacturers of the rust inhibitors and see what they say

Dad said he got them in 1968.

Just a warning. Refinishing old knives and guns can drastically reduce their value. Collectors tend to value natural pitina.

Get some oil on them first.

Keep them somewhere dry,until you figure out what you want to do.
