Have you seen this knife do any of these things in action? Will it continue to do so? Nobody has, or will, until this gadget hits the market. I remain skeptica

Have you seen this knife do any of these things in action? Will it continue to do so? Nobody has, or will, until this gadget hits the market. I remain skeptical in spite of your weird defensive reaction. I'm speaking about how a product appears to me as a professional. Not attcking you personally (unless it's your product... then I think you should do something good for society with your time)
