I'm new to the higher end steels and was wondering what you all use to prevent rust?

I got a Native 5 LW during Christmas time and haven't needed to check up on it till recently.

I took it fishing and camping, a little bit of rust spots started to form. They easily brushed off and there was no big problems. I've never used s35vn before and wasn't completely sure how to maintain it. So after the trip I applied some tallow like I do will all my carbon steel knives and sharpened it up. I also used some tallow to lube the action, and it seems to work well so far.

Do you think this is a good enough routine for protect the steel or is tallow a bit of over kill to you? Any recommendations for a common found lube for the action or is tallow fine? How do you all prevent rust from forming in the jimping, and how do you remove rust from there?

Thanks for helping,

Kevin
 
It doesn't matter what the steel is I use food grade mineral oil for all my knives it will inhibit rust oxidation and works well to lubricate pivots and such. It is also fairly cheap to get you may want to pick up some type of syringe for application inside areas of the knife.

If the tallow you speak is what I just read I would replace its use on your carbon knives with mineral oil as well.
 
S35V is actually incredibly corrosion resistant. I've never oiled any of my S30V blades and I haven't ever seen a speck of orange on the blade. My advice is to only wipe off the blade if you get blood or any other corrosive element on the blade, and to thoroughly clean it on occasion, especially if you just got back from camp or from a fishing trip.
 
I've never had a stainless steel rust, especially a PM stainless. I've left acidic food on S30V blades for weeks without issues but I guess I'm just lucky because I don't have issues with carbon blades either.

I don't think tallow is a good solution to lube and protect a blade. I'd imagine it would gum up the pivot and IMO it's completely unnecessary to protect the blade. S35VN should be good and stain/rust resistant without help from oils or protectants.

For the pivot some WD-40 or any one of the popular knife lubes would be good. For the blade, mineral oil is a popular choice but as long as it's clean and dry you shouldn't have issues.
 
Be careful with tallow, if it was not rendered correctly it can go rancid.

I tend to stick to mineral oil on my carbon steel knives. The only knives I currently have in S35vn has been in plenty of salt water, sweaty pockets, bags while camping and fishing, and I have yet to see any corrosion that didn't just wipe off.
I would worry too much. Just rinse it with fresh water, and dry it on your cleanest cloth (be it pants or shirt), and tuck it away for the next usage. You should be fine as long as it was wiped down.
 
the best thing that ive found is Fluid Film. you can find it at one of the big name hardware stores, i forget which one. its lanolin based, so if your allergic to sheep, its not for you.

dont use WD40, but WD40 Specialist. that will work far better, if you use something else.

for 100% food safe and on the cheap just use mineral oil USP from the drug store. it doesnt last long but they come in a big bottle for really cheap, enough to re-apply after you wash off the blade from whatever tasks you did.

honestly not sure how you were able to get rust on s35vn, i always wipe the blade after using it, and its pretty rust resistant in humid climate.
 
I have been using the knife for quiet some time now but never had any rust problems. This was the first time I used it while fishing, maybe I just didn't clean dry it off fully.

The rust spots were inside the spydie hole on the blade.

The tallow I have does not go rancid as far as I know. I've been using the same tin for a few years now and it's never gone bad. I use McQueen's brand tallow.

I'll try some different oils for the pivot. So far the action does not feel gunked up from the tallow, but I've never tried before so maybe it will after some time.
 
I wouldn't expect much issue with the tallow you seem to have good record with it but the risk of it going rancid and the potential for it to gum up are why I suggested before switching from it to food grade mineral oil. You can get mineral oil from the pharmacy usually as it is often sold as a laxative or buy online just make sure it is food safe/grade particularly if you use your knives in food prep.
 
I use Aegis edci solution before hand. Then I wipe down and reapply after corrosive environments.
 
I have many knives in s35vn, and have never done anything other than wipe them dry, even over camping trips by the ocean. No issues at all. Incredibly stain resistant.
 
I figured what happened to me was just a one time thing. Being the first time I really used the steel in water that much, I was surprised which probabaly worried me a bit.

I'm sure I don't need oils on the blade, just some lube and it's good. I just wanted to be cautious after seeing those tiny rust spots. Thanks for the help everyone. I'll grab some minimal oil later today and just use some of that as a lubricant.
 
Yeah, I'd check that out for authenticity. I have seen Native 5 clones on that Chinese cloner site that say S35VN on the blade but are made of something else.
 
I'm actually interested in this cause I've got a nice big sheet of Horween Chromexcel leather which would be perfect for a sheath for my S35VN knife but not being vegetable tanned leather I've been wary. I just don't know whether I can ignore this potential problem with a stainless blade.
 
Should take years of neglect to show surface rust, which can be scoured off, unless it's soaking in salt water

If you are going to use Mineral oil and your going to use it on food related stuff look for refined or food grade Mineral oil the unrefined stuff can cause cancer,read the link below.

I agree that you should look into it's authenticity. I watch Nick Shabazz on YouTube alot. He has reviewed alot of oils and lubes. If you go to his page and search for oiling a knife you should, he said that mineral oil as one of the options. Other options would be WD40 or Frog lube. Contrary to popular belief WD40 is not a lubricant it is a rust inhibitor. I also think it is odd that it rusted in the first place. YouTube has video's on how to differentiate between real one and clones. I would also call Spyderco and see what they have to say. I forgot to mention that Nick also recommended. Frog Lube as a rust inhibitor.
 
Try Pure Camellia Oil, That`s what the Japanese use on their knives and swords for centuries and it`s food safe.
