Abstract: A device that will allow individuals to uniformly slice bread. The unit will hold a loaf of bread and allow it to be sliced by assuring the positioning of the bread knife. This will be provided for by having corresponding sets of slots located on opposing sides of the device with the loaf of bread held between these slots by a fluidly variable closing mechanism. By engaging the knife in corresponding slots the individual will be allowed to slice the loaf of bread while limiting the range of lateral motion of the knife. This will assure the user of uniform cuts to the loaf of bread whether those slices are made at a ninety degree angle to the sides or at some other angle to the sides. Once a slice is completed the knife will be removed from the device and moved to an adjacent set of corresponding slots. The process will then be repeated over and over until the desired number of slices of bread have been cut. The cut slices of bread will then be removed from the device.
