Did not know that, thanks. I always had this idea that adamantium was super-sharp.
My other question that kept occurring during the movie was whether Wolverine should start having an immune reaction against the adamantium on his bones as soon as his healing factor stops working.

Well I don't think that one gets immune reactions with metals; one gets problems with metal toxicity which involves metals forming solutions in the blood and then chemically interacting in biological processes. Being so undamagable and thus presumably very unreactive and insoluble (as evidenced by a few decades of adamantium claws surviving being inside Logan and when not being inside the person he's stabbing at the time), I imagine that isn't much of a major factor with adamantium.
I think the metal toxicity has actually turned up in the comics though but even then I'm going to bet that it's something that takes a while.
The movie actually dodges that problem. Listen to Viper's talk with Harada, she says she subdued his healing factor, not neutralized it. Presumably there's still enough Healing Factor so he won't die of Adamantium Poisoning.
"All you Fascists bound to lose."
In the comics, the main thing that kills Logan when his healing factor is turned off is his body's inability to replace red blood cells. (The adamantium bone infusion pretty much wrecked all his bone marrow.) With the healing factor, of course, he's fine.
Being ultra hard means it can be sharpened to a much finer edge than any other blade can practicably hold (because it won't be dulled on the first hit, like normal ultra-thin blades), but yes, that still doesn't mean it should be acting like its mono-molecular or a lightsaber.
