<p>A rotary cutter blade for use in an unfluted constant diameter bowl of a small series motor driven food processor with a rotatable hub is provided where the blade comprises a cutting surface formed in two distinct curvatures of substantially equal radii with a first inner surface including a long circular outwardly convex cutting edge having its center of curvature offset a given amount from the hub axis and terminating inwardly of the bowl inner surface and having a second outer surface of a short circular outwardly convex cutting edge with its center of curvature being a lesser amount offset from the hub axis and extending from tangency with the bowl inner surface to terminate in a substantially pointed intersection with the first cutting edge and the first and second cutting surfaces having lengths substantially in the ratio of 3 to 1 where the particularly formed blade permits use of a series motor without stalling or jamming by wedged pieces of food between the blade and bowl. Preferably, the cutter is provided in pairs of diametrically opposite cutters extending from the hub for balanced operation with the opposite cutters being offset vertically in different planes.</p> |
