It’s easy to understand why people neglect their ice auger blades. The blades are relatively soft and require very little effort to cut. They are often not sharpened and are not adequately protected, which leads to accelerated corrosion, especially when stored in a damp environment.
A well-sharpened blade reduces stress on the motor and saves time during drilling. It also prevents the blade from jamming abruptly in the ice, making it safer to use.
For manual ice augers, a sharp blade reduces the required effort, resulting in faster hole drilling.
