The reverse side curved surface of described single cutter tooth satisfies surface equation:

-125.5+19.12x ₂-9.189y ₂-0.605x ₂ ²+0.5024x ₂y ₂-0.07687y ₂ ²-z ₂=0，

Wherein :-15≤x ₂≤ 5 ,-17≤y ₂≤ 3.

The obverse and reverse of described cutter tooth is staggered, and is conducive to weaken folder sword effect, strengthens the branch effect of breaking off with the fingers and thumb.

The utility model is copied badger canine tooth tooth structure, and badger is a kind of omnivorousness mammal, and its tooth is very sharp and hard, and this and badger tooth contour and structure have closely and contact, and this provides the important theory foundation for the utility model.

The utility model is long, laborsaving, efficient cutter life than common stainless steel.
