Knife for fine cutting work such as for graphic purposes, or the like

摘要

The base surface (15) forms a flat plane. The centering projection (19) has a trapezoidal cross-section, which decreases in size towards the base surface. A holder shoe with corresponding undercut groove (24) is pushed onto the projection from the front to form the overlapping holder. The holder shoe engages with its underside on the upper broad surface (28) of the replaceable knife blade (13). Trapezoidal centering projection and groove have releasable interlocking snap closure elements (35,34) on their rear ends.
