Numeral (3) - is the outer cover, which holds the blade holder with blade in it.
The outer sheath is made of approximately 0.50 mm metal sheet and is
provided with a rigidly fixed curved tailpiece. The outer cover is pivotally to the
grip portion so that its angle with the grip portion can be continuously adjusted.
Numeral (4) - is the grip portion which is normally made in two halves riveted
at two ends. At the top end the outer cover is fixed pivotally to the grip portion
by the top end rivet pin.
Numeral (5) - is the tailpiece attached to the outer cover provided for
comfortable finger grip. The tailpiece is usually made of plastic material and has
a suitable curved shape for comfortable grip.
Numeral (6) - is the bottom rivet pin used to hold the two parts of the grip
portion together.
Numeral (7) - is the top rivet pin used to hold together two parts of the grip
portion along with the swiveling outer cover and the tailpiece all together.
Referring to Figure II is the enlarged end view of the assembled blade
and handle. In the said figure:
Numeral (1) - is the ready to use narrow single edge blade.
Numeral (2) - is a blade holder, which is a sheet metal item, made of
approximately 0.30 mm metal sheet.

Numeral (3) - is a sheet metal outer cover made of approximately 0.50 mm
metal sheet.
Numeral (26) - is a metal round rod approximately equal in length to the blade
holder, which provides strength to the blade holder rail area and adds weight
and balance to the razor.
Referring to Figure III shows the razor handle and outer cover. In the said
figure:
Numeral (3) - is the outer sheath which holds the blade holder and blade at the
front end. At back end a small plastic tailpiece is fixed to the outer cover.
Numeral (4) - is the grip portion of the razor handle. It is usually made of two
symmetric plastic moulded pieces joined together by rivet pins located at the
two ends.
Numeral (5) - is a suitably curved plastic tailpiece attached to the bottom end of
the outer cover no.3. This tailpiece helps to provide positive grip when
operating.
Numeral (6) - is Rivet pin used for holding together the two parts of the grip
portion at their bottom end. The rivet pin is usually made of metal.
Numeral (7) - is a rivet pin used for holding together the two parts of the grip
portion at their top end along with the outer cover and tailpiece. The outer
sheath along with the tailpiece is free to swivel on the rivet pin relative to the
grip portion. When the outer sheath is swiveled inward to the maximum it
enters in between the two pieces of the grip portion, which then acts as a
holder for the cover.
