Method of making a knife having a scalloped cutting edge. |
摘要 |
<p>A scalloped cutting edge is formed on a knife blank (49) by disposing the blank between corresponding faces (41,43) of a punch (31) and die (33) assembly, whereby a resilient face (41) of the punch (31) compresses the blank into a plurality of scallop-shaped depressions (45) formed in the face (43) of the die (33), thereby imparting a corresponding scalloped configuration to the edge portion (53) of the blank.</p> |
