The Oliver Select™ and SelectPro™ commercial bread slicers are both equipped with our new, patent-pending blade cartridge system. Slicing blades no longer need to be changed one at a time. Bakery staff can now change the blades in a few simple steps that are easier and safer than traditional blade-changing methods. Interchangeable slice-width conversion kits are also available in the Select Series commercial bread slicers and come in 3/8" or 1/2" widths.
