This invention has to do in a general way with
cutting or scraping devices, and is more par-‘
ticularly related to that >class of such devices
which are designed to utilize razor blades as- the
cutting or scraping elements.
It. is the primary objectof this invention to
provide an improved razor blade holder which is
of simple form and construction and may be eco
l nomically manufactured, such` holder being so
lo designed _that it can be readily dismantled and
reassembled for the replacement of the cutting
element or blade. In this connection, my inven
tion contemplates a device in which the blade is
supported between two separate. jaw plates -hav
if) ing opposed faces formed so as to ñex the blade
when they are pressed together. In this way,'the
ñex resisting tension of the blade tends lto force -
the two plates apart. Associated with the sup
porting jaws or plates I provide a frame whichl
has its side ways adapted to receive the end por
Y tions of the plates, such ways being dimensioned
lso press the two plates together, thereby
flexing the blade so. that the tension of the blade
is utilized to hold the supporting jaws in fric
gr, tional engagement with the frame.
^ i
It is a further object of this invention to pro
vide a blade holdingmember of the class de- {
scribed which is constructed so that the bladei
supporting jaws can be completely removed from
:i the containing frame and reversed and reinserted

herein, reference numerals II and vI2 indicate
plates or jaws which have opposed faces I3 and

` t '
razor blade may be of any conventional type, 20
and, as is usual in the construction of such- razor
blades, it is provided with openings >I‘I--I‘l’
formedI along a medial line. In the present em
bodiment of this invention, I take advantage of
these openings to provide means for holding or 25
supporting the bladey against transverse move
ment relative to its supporting jaws. I accom-`
plish this by providing one of the plate members
(I I) with projections I8 and I8’ which are alined'`
»with openings LI9 and ‘I9’ in the other plate 30
member (I2), ‘such projections and openings be
ing situated -so as to fall into alinement with the
openings in the razor blade itself. In this way,
whenthe two jaws and the razor blade are as
sembled, the projections extend through the 35 ï
ing the jaws'and reversing their position in the _openings
-in~ the razor blade and support such i
in the frame to provide a holder for the scraping
or cutting edge which protects the same. In
this way, I have provided a device which' can be
easily carried in the pocket and in which the
