ABSTRACT:
The straight razor has a handle portion and a pivotable blade holder with a razor blade permanently and rigidly attached to the handle portion. The handle portion and the blade holder are made of economical easily used materials so that the straight razor is at least partially disposable. In one embodiment the blade holder is pivotally permanently mounted on a connecting pin joining two opposing parallel handle panels of the handle and the entire straight razor is disposable, while in another embodiment the shank portion of the blade holder has a recess in which the connecting pin is engagable so that only the blade holder and razor blade are disposable.
