as a putty kriifeblade, etc. A spring I5 prefer

Referring to the drawing, I0 indicates the
holder handle having a head lportion II which
may be offset rearwardly as shown, and is sub
tail in Fig. 4, interlocking engagement being ob
tained with a conventional razor blade by means
of the projections 2l extending through'the con
ventional perforations 29 of razor blades, or lat
, eral indentations 29' provided on blade tools
rwhich are not necessarily razor blades. rThe
plate 20 may have formations struck inwardly

vided with a flange extending at right angles
thereto to form the side walls I2 terminating in
inwardly extending longitudinal flanges I3 to
provide a magazine or elongated chamber where
extra blades may be kept such as razor blade Illy 55
also be readily understood that these studs may
likewise be formed on plate I'I at the like edge
so that it will extend between the two plates
when placed in registry. These Istuds in addition
to compensating for the thickness of the blade
being clamped act as a wedge to force the
2

clamped members together at the blade clamping
edges to more securely grip the blade. Thus
when the screw 24 is extended through the aper
ture I9 of plate I1 and threaded through the
aperture 23 of plate 20 and a blade placed be
tween the plates, the screw 24 may be tightened
so as to securely grip the blade at the forward
edges of the opposed clamping members and
aided by the wedging action of the studs 21 ex

my invention Without departing from the spirit
thereof and I do not therefore wish to be re
stricted thereto except as limited by the follow
ing claims.
