Bevel is a verb that means to change to a sloped angle. 

Coming from the Old English word for ‘open mouthed’ bevel has been with us since the late 16th century. It’s often used in carpentry, as a noun to refer to a sloped angle or a tool to create such angles. Here’s an example:

Rex has a tendency to get sloppy when trying to make angles by hand, so that’s why he uses a bevel. He feels it’s better to get the job done right than try to show off and have the result look bad.
