parts in proper relation. The shank also is formed
with an extension or tongue 2| which, when the
parts are assembled, will project over the o?-set
portion 3 of the holder member, one edge of this
tongue bearing against the side of the cylinder

at 22 in Figure 2, whereby it will engage over the
bend or o?f-set 4 in the lower member, thereby

the handle member are locked together against
endwise movement by and between the tooth 3|
and the lip 25.
When the device is to be used in honing or
stropping the blade, it is manipulated in the usual
manner for honing and stropping an ordinary
razor blade. To remove the locking member, the
lip 25 must be ?rst released by lateral pressure

proper relation. The end of the tongue 2| has the

the portion 3 of the blade-supporting member and
same formation as the end of the tongue l3 to
facilitate the entrance of an engaged part there
under. Upon reference to Figures 4 and 9, it will
be noted that the ‘counterpart formation of the
plates 3 and I1 provides a space between them
which will accommodate single edge blades hav
ing a thickened back edge, and it will also be
noted that the lip M on the side of the tongue 13

The oppo
site end of the strap is expanded laterally, as
shown at 21, and has one side edge formed with
a lip or ?ange 28 which is adapted to engage
against the back of the shank I5, as shown in Fig
50 ure 1, said lip or ?ange being slightly curved to
conform to and engage over the edge of the shank.
The inner end of the lip 28 is, in turn, slightly ex

between said expanded terminal and the strap 24,
55 as clearly shown. At its edge remote from the lip
28, the strap has a lug or tooth 3| formed thereon
which is adapted to engage over the front edge
of the shank, as shown in Figures 1 and 2. When

notch de?ned by and between the ledge 2 and the
portion 3 so that relative movement of the lock
will be prevented. It will be noted, particularly
upon reference to Figures 1, 2 and 3, that the
shank I5 is laterally expanded to merge into the
slidable extensions l6, I1 and I8, and the tooth
751K131 engages the shank at the base of the expanded
or fulcrum.
The device may be carried in a case or con
tainer which will be constructed to also hold a
small hone and strop.
Having thus described the invention, what is
claimed as new is:
