New methods, devices and measuring devices for slicing food are required for solving problems that occur with existing methods and devices and/or for reacting to changes to the food product being sliced. The devices include a blade for slicing food comprising a blade edge and a recess. The recess has a center point and may be employed for mounting and centering the blade on a slicing device. At least one dimension, D, of the recess is a length or diameter of the recess and preferably is at least 140 mm and at most 450 mm. The blade edge preferably has a radius, R, measured from the blade edge to the center point of the recess. The ratio of R/D preferably is less than 2.0 for every point on the blade edge.
