How many of you these days hang out in the kitchen expanded abundant to know that knives do get blunt in due duration?

The mechanism inside will automatically adjusts itself to match the

curvature of a wide range of blades. Pretty simplistic in design, but what are the physical hurdles that such a device must overcome before it becomes reality?
