User blog comment:Alpha Unix/Night's Edge vs. Muramasa/@comment-4524434-20111208143514

the muramassa might be better in some situations due to the fact that it can deal well over 40 damage in a mere second gives it somewhat of an edge over the nights edge. however, the edge has a longer reach, does more damage, and gives off more light. the edge is especially useful against anything that spawns after the wall of flesh as it does alot of damage. the muramassa is virtually useless against most of these creatures however.
