Nasus+Black Cleaver

Likely not, as Nasus should go pure tank since he gets his damage from stacking

eh, I don't see how Nasus would benefit more over Tri Force if you want a damage item like that. Trinity gives good damage for his Q

Hmmm, I doubt it. Nasus's only multi-hit abilities are his ult and Spirit Fire. Since these both deal magic damage, neither could stack black cleaver. He would need to stack it completely with AA's and with Q, which would rather slow. Nasus has a hard time reaching targets in fights, which is balanced by the fact he hits like freight train when he does hit you. A slow stacking item like that instead make his weaknesses more pronounced. Trinity Force gives even more movement speed (with both the "rage" passive, as well as +5% movement speed), and increases the power of his Q.

Spirit Fire already shreds armor without Black Cleaver. For his items you want to focus on tank and on enhancing his Q as much as possible.

It might be worth trying, but the damage from Sheen is very helpful early, and the benefits from Tons Of Damage gives him good overall stats.

It would work well on him with then full tank items.

Just wasted.

By the time he gets full debuff the person he is fighting will likely be close to dead.

Just get steraks with your tri or frozen fist. It's alot better

Black cleaver on Nasus was actually a thing prior the % E armor shred change. Now he doesn't need the item.
