A modular trowel handle device comprises a handle section to provide a handle interface for a user of the trowel handle. A post extends from the handle section and a mounting surface is coupled to the post and extends generally parallel to the handle section. A trowel blade receiving plate includes engaging structure configured to engage a connector of a trowel blade. The trowel blade receiving plate is coupled to the mounting surface and is formed from a different material than the mounting surface.
