I have some grease. It's that regular blue tube of grease for automotive marine, at walmart.
I have an experience. I let my 80$ shinwa katana rust all crazy. It was still great for cutting some things, but when it came to cutting heavier plastic, even after sharpening I had trouble cutting. I cleaned some of the rust off and put some oil on the sword, and it cut like it was never a problem . So, definately the more the material will squeeze the blade, the more the friction of the blade will matter. (duh, they say, but I just didn't worry because i didn't care if that cheapo sword was rusty, and wasn't cutting anyway., once I started cutting, I started with soft stuff and never bothered sharpening until I started to find resistance. after sharpening I still had resistance, which made me think of the rust.. actually, I've had plenty of conversations about smooth surfaces on blades, but was really worried about other things,,,, so anyway)
oil is slipperier, so probably it will cut better than grease. (hoho). but then, what's the word?? are there reasons other than it gets on everything to not grease instead of oil?? Is anyone greasing?? Or is oil (I have plenty) just easier, and better for cutting?

Depends on how much I used the blade as to whether or not I oil or grease it. Either way, thin is the word. Rub on the oil or grease, wipe the blade dry, then rub in some oil or grease from a rag. Don't apply the lubricant directly. If I think I don't have enough oil, I stop because that is just enough. Less is more.
Of the blade is stored for a long time then I will use grease. Otherwise, WD 40 and a wipe down. Never had any problems with rust or anything else.

I usually spray WD-40 on the blade before cutting especially if it’s one that I’ve had in storage and protected with LPS-3 or wax. The WD-40 will clean both off. After that, before cutting I spray again then wipe leaving a thin layer. I think this also tends to reduce the scuffing of the blade. After cutting especially where water is concerned I spray and wipe. If I intend to put the sword up for an indefinite time I’ll let it set a day or two after spraying with WD-40 before wiping again and applying wax or whatever. But I definitely spray with WD-40 before cutting. A thin coating of your favourite lub before cutting should help. Remember that lubs attract grit/dust whatever so be careful in that regard.

Or is oil (I have plenty) just easier, and better for cutting? WD40 is a Water Displacement product. Because it feels “greasy”, many people mistakenly think that its a preservative. Check out this guy's experiment page: www.dayattherange.com/?page_id=3667He compares 46 products, including WD-40, for lubricity and rust protection. Regular WD-40 does not do a good job of preventing rust. However, there is a WD-40 Specialist Corrosion Inhibitor product that is excellent at preventing rust.

LordNewport, excellent link to that test of products. Was glad to see the product Barricade did well. I use the forerunner to that called Sheath. A good friend that is a gunsmith recommended it some 30+ years ago. Sheath is only available in large quantities for industrial use now. Barricade is suppose to be almost the same product. Have heard good things about Frog Lube here and elsewhere and also complaints about the smell. Anyway, thanks for linking this.

I use WD40 or equivalents for cleaning, pure mineral oil for protection. Seems to work perfectly up here.
Thicker greases like petroleum jelly are good for long term storage and shipping of bare blades, but I wouldn't recommend them for scabbarded swords since they can accumulate in the scabbard, trapping dirt and moisture.
(And, of course, less is more as long as you get even and 100% complete coverage.)
