The further improvement project of the utility model is, the thickness of described blade upper surface is identical with the length of the horizontal bending of described connecting portion, and the height of described blade is greater than the length that described connecting portion vertically extends downwards.
The utility model further improvement project is, described blade is connected by sunk screw and described connecting portion, the nut outer face being used in conjunction with described sunk screw is the plane of sealing, all offers symmetrical dismounting groove on the outer face of described sunk screw, described nut.
The utility model further improvement project is, the counter sink coordinating with described sunk screw is opened on described blade, and the link of described nut embeds in the shoulder hole that described connecting portion offers.
The utility model further improvement project is, described connecting portion is provided with false sword, described false sword is the cutting edge that is opened in described connecting portion lower edge, and described false sword is parallel with the cutting edge of described blade, and the outer face of described nut is positioned at the inner side of described false sword place plane.
The utility model further improvement project is that on described false sword, equidistant intervals offers air drain along its length.
The utility model further improvement project is, described handle of a knife is the hollow structure that end is provided with opening, and the tail-hood that has been threaded on described opening, is provided with storage casket in described handle of a knife.
The utility model further improvement project is to be fixed with spring on the inner face of described tail-hood.
The utility model compared with prior art has the following advantages:
When one, turned and broken sword phenomenon in use appears in the utility model, replaceable new blade continues to use, saving sharpening link saves time and manpower, the flexible replacing of blade also makes the cutter hub of kitchen knife be reused, stopped in the past because blade is broken by the discarded wastage of material causing of whole kitchen knife, it is standby that user can buy separately blade, saves daily expenditure.
Two, connecting portion of the present utility model lower edge is made false sword and be distributed with air drain on false sword, at kitchen knife, cuts and can prevent that food materials are stained with on cutter hub while cutting food materials, facilitates daily use.
Three, in the utility model handle of a knife also with storage casket, can take in standby finding, when having demand, can take out in time use, on the tail-hood of handle of a knife, be also provided with spring, guarantee kitchen knife store in use casket not with the handle of a knife generation noise that bumps.
