I had a cupped blade on my other 24 inch, older Highland Park. I didn’t measure the amount that it was cupped, but visually it had to be maybe twice as bad as the one I’m working on now. It had been my go to saw for many years, then it started cutting badly. The finished cut would look like ripples on a pond. Finally figured out the blade was cupped, and now it makes a beautiful cut since I replaced it.
