Abstract
A molded plastic yet structurally rigid tool, such as a level, with a web extending in a generally undulating configuration. The undulating configuration of the web acts to strengthen and make the level more rigid when compared to a level with a planar web. The undulating configuration of the web is substantially symmetrical about the centerline of the level over its entire length, but may also be arranged in a number of non-planar embodiments.
