even if adamantium can cut through the organic steel, wolverine doesn't posses the strength to accomplish such a feat. i'm not sure who said this before me, but try to stab the sharpest knife in your possession through a foot thick block of solid aluminum. it isn't going to happen under your own power. you can slice at it all day and night, but it won't amount to any thing but... sparks.
and the eyes are debatable, because the same colossus that got his eyes poked survived a localized nuke and the pressures of the bottom of the ocean with no harm whatsoever to his "normal eyes".
oh and for the record, hulk skin is not tougher than colossus steel. what saves him is the instantaneous healing factor. yes hulk's skin is tough, but no it is not organic steel.
