Silver samurai for the knowledgable questions

Nope. He fought Wolverine recently in Wolverine: Origins and Endings Part III, he cut Wolverine's skin but no dice on the bone. However, Wolverine kicked his ass and cut off his arm with his own sword.

So normal bone? Yes

Admantium Bones? No.

If he had an admantium sword and the strength along with it, then yes he could probably cut through most of anything.

 

Heh, Silver Samurai gave him a really hard time, and you know these two have a history. It's a showcase of Logan's self control that he didn't kill him like he would have at one point and time, instead he just sliced his arm off...with Silver's own katana. He then told him to keep his honor because he didn't want it. Yeah, badass.
