I think it’s a really cool product. I would happily own one. The problem I have with it is that $400 is a LOT for a chef knife. A great knife and an awesome sharpener can be easily had for $150, or $250 if you get a top of the line sharpener. That knife will last you a lifetime. How long will this knife last? What happens when the battery runs out of lifespan. What about when the motor dies? If this was closer to $250, I’d be much more likely to buy it.
