A well-worn broadknife is better than a new one. The edge will be sharper and more flexible, and the corners will be slightly rounded. You can cut yourself quite easily with a broadknife, so use it with caution.
A broadknife is an indispensible tool, as it's useful for many tasks:
• spreading patching compound onto surface defects
There may be uses for cheap plastic scrapers, but in my experience a good steel broadknife is far superior.
