Who knew you didn't have to take an Xacto to your erasers to erase with precision!?
Having the right tool for the job is key for productivity. Improvising can work well at times but I've found that improvising can take up valuable time and can lead to unsatisfactory results.
When I was in my earlier years in school I used to use an Xacto or Olfa knife to sharpen my erasers when there was a small area that needed to be fixed or erased. Once I found the eraser pen though, it saved me tons of time and I could see a noticeable difference in the quality of my erasing which is important on final drawings! Watch below to see the eraser pen in action.
