Our patented composite knife delivers long-lasting performance. The 13" CleanCut™ knife is a stainless steel knife with a stellite-alloy edge. While lesser knives will dull quickly or pit, ours stays sharp longer, giving you unparalleled precision. Using this alloy, we’re also able to create a thin-edge design, so you get improved yield and reduced cost of ownership. In fact, the CleanCut knife outlasts other knives on the market. Our Borazon® sharpening stones, with a lifetime warranty, ensure it. The sharpener is top mounted on the HS Series slicer and is easy to operate while keeping the knife edge shielded.A great knife isn’t the only thing that yields consistent cuts. The HS Series product tray is designed to enhance the quality of each slice while working together with the removable, rear-mounted, meat-grip assembly to ensure secure product placement. Machined grooves on the gauge plate and knife cover ensure smooth and even strokes, reduced drag, heightened precision and improved slice performance. For added precision, the HS Series automatic models are equipped with three stroke lengths and four stroke speeds to handle a wide variety of products. The automatic models now also come with a seamless fence to secure the product during automatic operation.
