Occam's Razor is a unique combat knife in Fallout 3.


Commander Jabsco's personal weapon, Occam's Razor, is stronger than the basic combat knife in raw damage by a total of 3 points. It is aesthetically identical to the normal variant.


Occam's Razor can successfully strike about 1200 times from full condition before breaking.
