Implement the "Pro Tip" for Blade Maintenance

What happens here

Following the observation of a dull blade's poor performance, a crucial 'pro tip' is offered: 'change your blade every now and then, man. I was working too hard.' This advice underscores the importance of regularly replacing or sharpening your scraper blade to maintain its effectiveness. A razor-sharp blade ensures that material is removed cleanly and efficiently, without damaging the wall surface, thus saving time and effort.

Goal: Ensure the scraper blade is always sharp for optimal performance and wall protection.
