This `invention consists in an improved mag
azine ~for containing thin flexible safety razor
blades in a novel stacked Aformation with the
'blades spaced at one end of the stack by inter
leaved shims or extension pieces thus facilitat
ing the separation from the stack of one blade
at a time and its delivery from the magazine.

arating one thin blade after another from a stack
