PERFORMANCE: Exceptionally powerful high torque motor with gear drive. SLICING: Slicing is facilitated by a tilted food carrier. When the machine is not in use, a specific button locks the food carriage in the lock position, preventing access to the blade. MULTI-PURPOSE: The 7-inch stainless steel blade slices a range of items from deli thin to 3/4-inch thick; this product is intended for personal use only.Slicing is quick and efficient with the tilted large-capacity food carrier and cantilever design. Food carriage blade food pusher food deflector and thickness guide are easily removed for cleaning. At the base of the slicer, there is a safety fuse for surge protection. Model 601 is a recommended blade sharpener. Although it is made of plastic, it is rather remarkable. We had a slicer that cost approximately $100 (can't recall the name) and practically every time the meat came into contact with the blade, the gears skipped, making it a pain to operate. Now we have this model, which is incredible. It truly slices as quickly as the flesh can be slid through. It's fantastic!The carriage that enables you to feed an object into the slicer retracts to a distance of about ten inches between its handle and the blade's surface. Thus, a ten-inch-diameter object may be sliced into a ten-inch-diameter slice. You could produce a longer slice, but then you'd have to feed the food in manually and watch your fingers... The 615 is quite simple to disassemble for cleaning. To be honest, I have five thumbs when it comes to mechanical engineering, and I have no issues. It is not a difficult piece of equipment to operate. Why would somebody cut a shoe heel with a food slicer? There is a saying on tool usage... " Use the appropriate tool and use it appropriately." Or similar expressions. I believe it is one of the most well-designed slicers available. Especially in light of the money.
