The utility model relates to universal blade formed steel used for fabricating a universal blade for carrying out the operation of rotary cultivation and stubble cleaning. The utility model is formed by the combination of a straight line segment and a convex curve line segment; the thickness delta of the utility model ranges from 5 mm to 8 mm, and the width b of the utility model ranges from 40 mm to 60 mm; the length of the straight line segment ranges from 60 mm to 120 mm, and the arc length 1 of the curve line segment ranges from 150 mm to 250 mm. Blank materials and proximate matter used for fabricating a universal blade simplify manufacturing procedures of the universal blade; not only manufacturing cost is lowered and production efficiency is raised, but also the utility model is favorable for the production of minor enterprises in remote and undeveloped areas.
