Thank god for nose grease!

I've known about this since I was a kid (a long time ago- well, actually still am). It works well enough that Ed Fowler recommends it. I do however wipe off my blades before cutting food.
 
There is also plenty human oil behind your ear. Some folks touch a piece of carbon steel and leave rusty fingerprints almost immediately their natural skin oil will not work.

An experiment in micro biology years ago suggests our bodies also naturally secrete some defences against bacteria.

Most of us are blessed, and have a life time supply of the finest lubricant and rust preventative where ever we go.
 
That would be me, I'm a rust inducer. :(

Nose grease works well for scratched up CDs as well.
 
One of the Lee Child/Jack Reacher novels turns on the use of squalene, which is a high grade lubricant found in only two places: shark livers, and the sides of a human nose. Apparently jewelers use it in repairing fine watch parts, so you'd think it would be OK for knives. However, that's a novel and the salt/acid content is probably filtered out of the commercial stuff.
 
as I'm reading this, I had just finished sanding a little 1084 knife I made a couple of months ago that had some rust spots from just sitting unused inside it's kydex sheath. I had no idea about the properties of nose grease but had done it in the past, swipe the outside of the nose and rub a blade. Now this little knife is thoroughly done with what little grese there was on my nose, so I think I'm gonna do a test and leave it outside the house for a week and see how nose grease holds up. thanks for the info.

Didn't anyone's dad teach them to use nose grease to lubricate the pieces of your fishing pole when putting it together?

Ha, thanks for the link. I use the oil from my nose to get tape gunk off of knife blades (it dissolves tape gunk better than anything I've ever tried), and I always speculated that the oil in your nose pores was different from the rest of the body, but I never actually looked into it. This confirms it.
 
doing a little testing of my own. Have a little knife sleeping outside for 3 days now, rubbed with nose grease and on a Kydex sheath, checked it this morning and no sign of rust. I'm gonna leave it out there a whole week and see how it fares, and then I'm let it gonna sit for a couple more days out of the sheath.

Don't know how warm it is there now, in Florida. But, it would be interesting to see/hear results from the same 'testing' done in summertime, when sweat is more of a factor. I know, when I've really sweated a lot, the salt in the sweat is much more evident on my skin. Can sometimes even see/feel it's grittiness when the sweat dries on my skin. The salt is what I'd be concerned about, with a carbon steel blade.

well, decided not to wait and took it out of its sheath yesterday and left on the bbq side shelf. As luck would have it, it rained last night. It had just the slightest faint trace of rust on the edge and it came off when I ran a finger over it

a little rust spot on the handle over the 2nd hole. Less grease there as that is the spot where I grab to pull it from the sheath

left it there and went back inside. A couple of hours later a good downpour was falling. Will check on it again tomorrow, but seems like the grease is working. I hear you on the salty sweat issue, but heavy rain is also a good rust inducer.
