From what I've read, grind issues are one of the major and common issues with all knives; overground knives can be more flexible than correctly ground knives, can cause a knife to steer because one side of the knife is ground more than the other, and can cause a knife to not cut smoothly, among other things.
However, I'm not sure what to look for. I have knives that are more flexible than expected, knives where one side of the knife seems to be ground more (the grind seems to go higher than the other side). But, I'm not sure these knives are overground or incorrectly ground.
What are clear markers or things to look for to identify grind issues?
