Identify Issues with Dull Scraper Blades

What happens here

The video begins with the sound of scraping, quickly followed by the presenter's observation, "Jeez, razor sharp," delivered with an ironic tone. This statement, contrasted with the visual of the scraper leaving marks on the wall rather than cleanly removing material, immediately highlights the problem of a dull blade. A dull blade requires excessive force and scratches the surface, making the job harder and potentially damaging the wall.

Goal: Understand the poor performance and potential damage caused by a dull scraper blade.
