I know that those who can't look at the pictures I provided and understand the different kinds of sawing don't know enough to be posting on this topic at all.
When one of those know-nothings starts questioning me, or anyone else who has direct knowledge of the subject, the first thing we usually do is politely inform them of our experience. That is not bragging. If they persist, then they are being rude and obnoxious, and I really no longer care about their embarrassment and feelings of shame.
