A kind of agricultural edge structure before processing,System includes: an agricultural blade,The agricultural blade end forms a binding end,Binding end forms forward a first surface and a second surface,This first,The left side and right edge on two surfaces are set as toward oblique inclined-plane,And make the left side and the right edge system tapered bevel edge forward,Mainly on two inclined-planes of the two bevel edges position simultaneously punching zigzag fashion majority tooth form,And make the surface tooth target tooth form,Back side tooth is the tooth form for offseting punching stress,It is such so that the second surface of pressure-bearing keep it is smooth will not because of pressure initiation concave arc,Can be not required to largely to cut in Hou attrition process can at being a flat surface,The person that is conserved material.一種加工前之農用刀刃結構,係包含有:一農用刀刃,該農用刀刃末端形成一結合端,結合端往前形成一第一表面及一第二表面,該第一、二表面之左側邊及右側邊設成往下斜之斜面,並使該左側邊與該右側邊係往前漸窄之斜邊,主要在該兩斜邊位置的兩斜面上同時衝製鋸齒形狀之多數齒形,並使該表面齒為目標齒形,背面齒為抵銷衝製應力的齒形,如此得以使承壓之第二表面保持平整不會因壓力形成凹弧,在後製研磨加工時可以不需大量切削就可成為一平面,得以節省材料者。
