All this talk about cutting food in the kitchen has me wondering: what surface is most/least harmful to the blade? I mean, when you cut through the food to whatever it is resting on, such as a plate, formica or stone countertop, wood cutting board, glass cutting board, plastic cutting board, etc. Which of these can roll or dull the blade the most/least?
I'd love to get my wife a nice kitchen knife, but she usually cuts on a glass cutting board and I suspect that the glass is not good for the blade. She won't change her habits. Would the blade metal make much difference? For instance would D2 stay sharp slicing into glass cutting board or ceramic plate?
BTW, I'll use a folder on food in the kitchen if it's the sharpest thing around (usually is -- see above), but try hard not to let anything get into the pivot or scales.
Also, I use peanut oil to coat blades that I will use for food. Peaunut oil never goes rancid and doesn't cause the problems that mineral oil might, unless a peanut allergy is involved.
