| Back in 1956 Alfred BOrner a toolmaker by trade developed a method to manufacture razor sharp thin blades and to bend them in such a way to make cutting onions into cubes easy work. This prototype was made of wood. Almost 50 years later this tool is now constructed of 18/10 stainless steel with German surgical steel blades.18/10 Stainless steel body German surgical steel blades Improved blades cut in both directions Stainless steel neutralizes odors Easy to clean Dishwasher safe |
