Byte magazine described a new product called the MacKnifer:
"Ennui Associates has announced MacKnifer, a hardware attachment that mounts on the side of your Macintosh and sharpens knives, scissors, lawn-mower blades—anything in your home that needs sharpening. With MacKnifer's patented double-action grinding wheel, you can easily sharpen any utensil in less time than it takes the Mac to open a file. According to the manufacturer, MacKnifer is so easy to use that you can operate it within 30 minutes of taking it out of the box. Turn your spare computing time into extra cash with a knife-sharpening business on the side... of your Macintosh."
