<p>Conventionally, since the edge portion has a wedge-shaped cross-section bulging to the opposite sides and a kitchen knife is used in a dull state, an onion is cut while being mashed at the time of chopping so that an irritating odor is scattered to thereby causing a pain in the eyes. In addition, in the final process of mincing, the onion is cut while being mashed because up/down operation of the kitchen knife is repeated thus bringing about a more terrible condition of the irritating odor. A manual knife comprises a thin planar knife body (1), a continuous zigzag edge portion (2) formed in the knife body (1) with an acute angle, sharp pointed edges (2a) formed at the projecting portion of the edge portion (2), and slice edges (2b) formed symmetrically from the pointed edges (2a) toward the recessed portions, wherein one side provided with the edge portion (2) has a curved shape bulging by 0.2-1.5 mm, anti-break portions (3) are provided on the opposite sides of the edge portion (2), the knife body (1) is replaceable and a grip portion (4) is formed arcuate.</p> |
