Description
Technical field
The invention belongs to cutter making fields, more specifically more particularly to a kind of dagger.Meanwhile the invention further relates to
A kind of manufacturing process of dagger.
Background technique
Stainless steel knife has been widely used in the production and living of people, and with the improvement of the quality of life, people are not to
The Steel Properties that become rusty require also higher and higher.Since cutter contacts the media such as water or organic matter for a long time in daily life, cutter holds
It is easily corroded, breeds bacterium etc. and then influence people's health, crimping even notch occurs when using in addition and influences cutter
Using and it is beautiful.In order to overcome stainless steel stiffness issue, nitriding, carburizing or carbonitriding usually are carried out to stainless steel, improved not
The surface hardness and wearability of rust steel, but existing stainless steel and stainless iron antirust ability are imperfection, in severe ring
It also gets rusty under border, influences the use and beauty of cutter, and the connection of the handle and blade of present dagger is relatively simple,
The problem of connection loosens is easy to appear under larger external force, and existing dagger handle does not process, handle be easy it is mouldy,
It addles.
