Abstract: Apparatuses are provided for various tools that incorporate materials with a high coefficient of friction and a low coefficient of friction. The materials with a low coefficient of friction may be mounted on a tool and have a perpendicular movement to the tool. This perpendicular movement may be implemented with a spring mechanism.

The tool may be pressed against a surface, first engaging the materials with a low coefficient of friction. The tool may freely move across the surface while the materials with a low coefficient of friction maintain contact with the surface. As the tool is continually pressed to the surface, the materials with a high coefficient of friction subsequently make contact with the surface, thereby causing the lateral movement of the tool with respect to the surface to be restricted and stabilized. An example of the tool may be a spirit or carpenter level.
