Abstract

PURPOSE: To avoid production faults such as cracks due to hardening or tempering and/or knife-edge cracks due to aging, by press-punding after having internal deformation stress balanced then hardening, tempering and knife-edge-machining a clad plate while having the internal deformation stress remain therein as it is.
CONSTITUTION: A body portion of a clad plate for a kitchin-knife production is cold-hammered to form a hammered pattern thereupon. Therewith, an elongation is generated also in a knife-edge steel portion which is to form an intermediate body of the knife. Hence, an internal deformation stress is balanced by giving a full- surface elongation to the portion which is to form a cutting edge portion of the clad plate. Thereafter, the clad plate is press-punched into a kitchin knife shape, roughly.machined and finish-edge-machined while having said internal deformation stress remained therein for a hammer-patterned kitchin knife with a cut-edge portion 1 and a body portion 2 to be produced efficiently and also for its sharpness to be increased drastically.
