    +1 Yeah, it's onlt relevant with knives in longterm storage/neglect.

    I don't use mineral oil anyore b/c of it getting gummy on me. Well, maybe not gummy, but it definately thickens.

    I always see that choji oil for sale with sword stuff. What's it made from?

    Choji oil is a mix of mineral and clove oil. I think.

    Fluid Film. Food safe and very effective.

    ??? The Bay Area gets about the same rainfall as southern california. Hell, SoCal has had a TON more rain than the bay area so far, we've just had a couple days of light rain here and there.

    Unless maybe you're in the more Santa Cruz areas....

    Never had a problem with rust here, even on 1095 which will rust/patina MUCH faster than CPM M4. But I use Mineral Oil. Odorless/tasteless, cheap, etc... :p Keep them dry, and wipe them down after use. wipe them down with an oil rag before bed. done.

    Yeah, I must admit I havent felt the urge to test its bowel clearing properties but I do know it is available in capsule form so I guess there must be something in it! I just use my knives to cut food quite a bit so I always use it just to be safe. I also use Break-Free and Tuf-Glide for pivot areas and WD-40 to clean G10 but Ballistol gets used on the blades. ;)

    I typically wipe my EDC (the m4 millie right now) down with tuf cloth at night.

    well, I skipped last night, was out side in the rain a bit this morning, and had light rust dusting on one side of the blade!! I was pretty worried, but did some research, and some comet on a tooth brush took care of everything, and didn't leave any scratches or anything!

    A close call, but it's a good lesson for me to take extra care of this m4 steel.
