several blades are provided, in which two guides are arranged for each blade for slidably holding a blade abutments are arranged in the holder and also on the holder and on the blade, in order to limit the sliding movement of the blade in the holder lock when the blade is in its correct position.

The invention is schematic and example in the drawing shown. Show it:

Pig. 1: a perspective view of a blade, Pig. 2: a perspective view of a holder and 3: a perspective view of a holder in one further embodiment.

The blade 1 shown in Figure 1 has a cutting edge 2 at one end, a cavity 3 and two abutments at the other end 4- and 4 · 'in the vicinity of the end provided with the hole 3 of the Blade 1.

The abutments 4 and 4- 'are on the long sides of the blade 1 through punched cuts are formed and angled to a certain extent with respect to the blade.

The cavity 3 is there to a hook-shaped tool in the Insert the blade so that it can be easily removed from the holder 5 can be.

To insert the blade 1 into the holder 5, the blade 1 is ^{pushed into the guides 6 and 6 1} with the cutting edge 2 first in the direction of the arrow 7 until the abutment 4 engages in the recess 8 and thereby locks the blade in the holder.

When the blade 1 is inserted into the holder 5, the "hinge" is slightly bent up so that the abutment 4 can be guided over the switch 9. Is allowed to spring back, the blade 1 then 4 engages the abutment in the recess 8 a, whereby the like longitudinal movement of the blade is prevented.

A bevel 14 is provided so that the blade is easy can be pushed into the holder until the abutment 4 engages in the recess 8. This bevel 14 makes it unnecessary that a person has to insert the blade into a holder up to its entire length.

The blade is also thus retained at one end of the holder by the holder encompassing the edges of the blade. This encompassing is effected by the blade, which ^{presses the guides 6 and 6 1} apart so that the holder is under tension at 10, whereby the guides are caused to encompass part of the longitudinal carriages of the blade.

arranged so that the distance between the guides is a little less than the width of the blade. Thereby, if it is surrounded the blade 1 between the guides 6 and 6 ^1, the same pressed apart against the spring action of the retainer> at 10, whereby they engage around part of the longitudinal edges of the blade 1 firmly.

Removing the blade from the holder just becomes a hook-like one Tool inserted into hole 3, the blade is bent so that the abutment 4 can slide over the shoulder 9, whereby the blade can be pulled out of the recesses 6 and 6 '.

A hole 13 can be provided at the end of the holder in order to form a strip-like attachment against which a tool is attached and how a lever can act to lift the blade from the slot 8 before it is pulled out.

As shown in Fig. 3, a second Aus ^ prung 8 'with a Shoulder 9 'may be provided so that the blade can be withdrawn in the holder to a position where it is ineffective, e.g. H. is in a non-cutting position without removing the blade from the holder.

The front edge of the recess 8 'is provided with an inclined ramp surface 15 so that the blade, when it is held in the slot 8 ¹ , is pushed slightly forward in the direction of the arrow 7

to safely store them in their cutting position at 8. At the bottom of the holder can be done in a similar way as above described, a second blade can be arranged.
