At any rate - great integration design! I disagree that LMF adds a firestarter at no consequences at all. It is adding weight and complexity to the system - no doubt. The solar mirror on the knife is truly ideal device (when inventor solves a problem - the ideal solution would be "nothing new added, but problem solved") as it is factually nothing you could break or lose. Compared to a fresnel or typical 5x loupe (usually small and thus quite useless) it has much more light concentrating potential than either (the surface size is ruling here). I agree, it can get scratched with time, but if so - you can polish it back as well easily enough. Overall it could be perfect for a minimalistic kit, which is not constantly in use, but waiting for an emergency.

A question to knives gurus. Is it good enough as a knife? (does it worth $60 regardless the mirror?)
