Abstract: A cake slicer that, during operation, cuts in a truly linear fashion and efficiently transfers loads generated in the saw blade from the blade to the base. The cake slicer includes a rigid saw blade assembly that linearly reciprocates between two bearing blocks. The saw blade assembly includes a blade tensioning assembly that helps retain the saw blade to the frame of the blade assembly and allows one to adjust the tension of the saw blade. The cake slicer also includes a coupler to connect the rigid saw blade assembly to a motor. The Coupler includes a half coupling with drive pins and a drive pulley with drive-pin recesses that receive the drive pin. The cake slicer also includes a plurality of weighted rollers to prevent unintended elevation or declination of the cakes during operation.
