Double-edged knives (34,38,40,68) for use in centrifugal-type cutting apparatuses, for example, the Urschel Model CC®, and transverse cutting wheel-type cutting apparatuses, for example, the Urschel TranSlicer 2000®, to produce uniform cuts in bulk quantities of food products. Such a knife (34,38,40,68) has a longitudinal length defining oppositely-disposed first and second ends and defining oppositely-disposed edges (35,41,60a,60b) between the first and second ends. Each of the edges (35,41,60a,60b) has a cutting edge defined thereon adapted for slicing food products. As a result, the knife (34,38,40,68) has two operational life spans and can be removed and reinstalled to utilize either of its cutting edges.
