Abstract
A two-sided casing chisel has two chisel blades that are mirror images of each other to enable one tool for chiseling and cleaning the doorway casing on either side of the doorway. The two-sided tool simply has to be flipped around to allow cleaning of doorway casing on an opposing side of the doorway. The chisel blades may be coupled to a blade assembly that is detachably attachable to a handle assembly. The blade assembly may have a first end and second end each having a two-sided chisel blade or sanding ends with an abrasive material to allow sanding along a doorway casing. The blade assembly may be reversible to allow a user to flip the blade assembly upside down to expose second end which may have sanding ends for sanding or a second set of chisel blades in the event blades on the first end become dull.
