Ice scraper

Alternatively, the handle can be inside a thumbless mitten to help keep the user's hands warm and dry when using the scraper.

Plastic blades tend to have a more complex shape with several thick "fingers" linked together.

[citation needed] This form helps the blade to flex, since most modern car windows have a slight curvature.

The "fingers" also often have ridges on top, so the scraper can be flipped over to break up thick ice.

[citation needed] More complex designs exist to improve ice clearance on curved glass on automobiles.
