This is a magnetic latch for holding doors shut. I use it on my closet doors that have the balls that get jammed all the time. I use 0.25" by 0.25" cylindrical neodymium magnets purchased from amazon. They require tiny wood screws. The magnet that mounts parallel to the surface will probably need to have super glue on it to hold it in. These were created in inches, so your slicer will probably need to scale them up.
