Abstract (en)

[origin: DE19618803A1] A ceramic blade (1) of a cutting tool particularly of a knife, with a cutting edge (10) and a rounded upper edge (12) situated opposite the cutting edge (10). As opposed to the sharp-edged transitions found up until now, the rounded upper-edge (12) significantly increases the resistance to breaking in case of bending.
