The proof of the pudding is in the eating. I’ve eaten both, side by side, because it’s a really interesting difference. A cheese slicer makes a wafer thin piece of cheese that I cannot replicate with a knife. It is not a skill issue either. A chainsaw and a fretsaw produce different results, regardless of the skill of the user.

However you’ve decided that your reckoning is better than my experience, which is astonishingly arrogant.
