The present invention deals with blades of a
type which it is desired to ‘protect at the time
and place of manufacture by enclosing them in a
wrapper or envelope. The wrapperoverlaps and
safeguards the sharp edge or edges of the razor
blade and must be removed eventually to make
the blade edge accessible "for ‘shaving; It has
sometimes happened that in stripping the wrap
per or envelope from a blade already positioned
in a razor the envelope has become entangled
with the razor and has been torn, leaving a por
tion of it in the razor instead of being withdrawn
intact. Such an occurrence is an annoyance to
thev user because the torn portion'of the wrapper 50
must be extracted from the razor before it can
