Yes, when you use the scraper, the correct way is to push and use your thumbs to put a slight bend in the spring steel scraper. From my experience using them the heat build-up on your thumbs can get hot enough to blister at worst. or sustain a minor burn on the skin of your thumb. that is one reason I never used the scraper as much as I should have. The holder insulates the thumb plus puts a consistent arc in the blade.
