This invention relates to improvements in a razor and like blades, >and which is adjustable to or the screw driver I4', or other like blades such as a putty kriifeblade, etc. A spring I5 prefer ably in the form shown such as a U-shaped variouspositions so that it can be used for a member formed with bowed legs, seats under scraping and cutting tool adapted to utilize safety multiple of tasks, and is a continuation-impart ¿Í the ñanges ¿I3 and holds the extra blades in place regardless of their number, limited by the of my co-pending Aapplication Serial No. 97,529, depth of the formed chamber. Thus an extra filed August 24, 1936. Y supply of blades is always on hand and ready for One of the objects of thi-s invention _is to pro vide’an improved blade clamping portion or unit usewhen fragile blades such as razor blades be which will firmly hold a blade through hard 153 come worn Iand broken, or the chamber may be used for storing convenient extra> tools Such as usage, lsuch as when used for scraping, cutting, and the like purposes.

Fig. 7 is a detail in perspective of the blade clamping members shown in Figs. 2,k 3 and 4. Fig. 8 isa detail in perspective of the blade clamping unit shown in Figs. 5 and 6. _ ` ' 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 therefrom such -as 26 at its rearward edge'o-p posed -to thenblade clamping vedge to» provide stantially of the width of a conventional razor studs on its under surface such as at 21. It will blade. The handle portion illustrated, is pro 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 2,267,964 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 arranged and changes made within the scope of 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.
