If I was gonna go all Deadpool on him, dual katanas, decapitation.

我会用死侍对付他，用两把武士刀将他斩首。

Secondly, katanas were made more for slashing strikes that could bleed an opponent to death, and zombies are notoriously immune to bleeding to death by virtue of already being dead.

其次，武士刀更多的是用来进行可能使对手流血致死的猛烈攻击，而众所周知， 僵尸因为已经死了而不会流血致死。
