Medical grade "mineral oil" on all my HI Swords and Kukri's

Once a year I put a coat of medical grade mineral oil:thumbup: on my blades. I have never had any rust in 7 years. Minieral oil is non-toxic (human can drink it) and its dirt cheap. In some Japanese blade forums they claim medical grade mineral oil is close to what was used in the old days.

Anyone else use this?
 
I used to apply silicone oil on my sharpies. It's innate by nature.
But humidity is an issue for storage. Having to stay along the coastline doesn't really do any good to high carbon steels.
 
"Medical" grade? Do you mean for laxative use or for massage oil? :))))))))))))))))))))
Which brand do you use? I just get the generic version from Target or WalMart and it lasts me forever.
Mineral oil is great and along with Ren Wax you have all the basics covered.
 
I have used it for many years, it works great. I recently been using Renaissance wax for all my blades, Great product can be used on every part of your blades. Mineral oil is a very inexpensive alternative and never failed me.
 
As soon as my kukri is delivered it goes into a Mineral Oil bath so the handle can soak up all it wants. I take it out let it dry and then apply a little bit more mineral oil to the handle and then its good. I also repeat this after the kukri gets wet and after a stretch in the polaris. I also keep a good coat of mineral oil on the blade when it is being stored, no rust issues.

My Bonecutter sees a lot of regular use as my farm vehicle kukri so for day to day touch-ups and regular rust maintenance I use WD-40 on the blade. It is fast, easy and there is always a can around. Just spray it on, wipe of the excess and you will never have a rust issue. Also, a quick spray here and there when you are doing extended chopping works wonders on the blade's performance and eliminates sticking in the wood. (of course don't get any on the handle!)
 
How different is medical grade from food grade? It's also great for wooden chopping boards and wooden handled kitchen knives.
Because I oil my boards and knife handles more than once a year, I tend to use Sunflower oil rather than Mineral Oil, but it has a "shelf life" of around 14 months.
Choji Oil is usually either Mineral Oil or Camelia Oil with a hint of Cloves.
 
I use olive oil on my food prep HI Knives (yeah, I've got about 5 that I use nearly daily for such things:D)
I use baby oil on the rest of them. I stocked up on the stuff before my daughter was born, but I have never used it. She was born without a dip stick, so I have no idea how to check if she needs any. It's been 19 months, so I'm sure she's at least a quart low. Also, where do you put it in? The front? She's not European, so I don't think it's in the back:confused:

yeah, that joke never gets old:p
 
I use regular food grade mineral oil on all my khuks and swords, including the handles. Its cheap odorless and won't go rancid. You do need to be a little careful because it will soften and discolor leather. However, I've found that with the wooden framed black khuk scabbards that's not a problem. I did stain a nice leather sheath that Dan Koster had made for me when he rehandled my HI bowie knife because I used some mineral oil on it.
 
Mineral oil is perfect for all natural handle materials, horn, stag, rams horn, ivory, bone, etc. It keeps the horn from drying out and shrinking so much, which gives you that pommel edge. I would use it on blades without hesitation, but always use AG Russell Rust-Free or Ballistol instead with good results.
 
I use camellia oil, which was actually used on Japanese swords back in the day. No noticeable smell, no taste.
 
I usually leave a very thin film of gun oil on most blades. My knives never rust. Kitchen blades get the choji oil I put on my two swords, I just clean it off before using them.

Tried VpCI once, seems to work but it makes everything smell like artificial maple syrup.
 
Can someone please explain what you mean by "medical grade" mineral oil. Several people have used this term in this and other threads.

I just did a web search and found all kinds of mineral oil, but nothing explicitly described as "medical grade."

The closest match I found was a comment that mineral oil comes in light or heavy varieties, and that the light variety is used in drugs. Is that what you mean?

I am planning to give my new horn-handled khukuri a mineral oil bath and I don't want to use the wrong kind of mineral oil and made a mess or do some damage.

The pharmacy section of stores should have 16oz containers of mineral oil on a shelf with the laxatives. The bottle I have in front of me says "heavy mineral oil USP" where the USP means it meets the relevant standards for pharmacy/medical use. The listed dose for adults is 1-3 tablespoons per day, so I guess it can also be considered "food grade".
