Thus, humans were accelerated to apex predator status (in part) by the ability to visually differentiate green and red.
The range of wavelengths we perceive as red is much larger than the range of those we perceive as green. [red=620-750 nm (130 nm range)... green=495-570 nm (75 nm range)] Which is why it's harder to make green than red.

A good way to get a really, truly sharp knife is to use the Lansky sharpening system and finish off with the sapphire honing stone. It basically polishes the honed surface to a mirror finish, and you end up with a blade as sharp as a razor. Just make sure the knife's blade is a good high-carbon steel, as no form of stainless can hold an edge like high-carbon steel. Even better, make your own knife by grinding down an old mill file (it has to be an old one to get good solid hardness, the newer ones are just case-hardened).
