Besides the old stand-by of an over-ripe tomato, what food items have you found to be a good sharpness test?
Roma tomatoes seem to have a thicker skin, but they're also pretty small. The "regular" red tomatoes (approx 3.5" diameter), when you slice them very thin, produce a fairly fragile slice that seems to be a pretty good test to see if you can make a full slice without any tearing.
Potatoes are OK, but the problem with those, with a non-dimpled knife, is the vacuum created from the juices as you slice causes a slicing resistance that has little to do with the sharpness. But if you first cut in half and then just do very thin "potato chip" slices with just a downward push motion, the resistance seems more proportional to sharpness.
What other food items do you guys like to use (including meats, not just fruits and vegetables)?
