What is the significance of the working tools in Freemasonry?

The working tools serve as moral allegories for building personal character and functional symbols of governance within the lodge.

The common gavel signifies the process of divesting one's heart and conscience of vices and superfluities, removing rough excrescences to reveal the refined individual within 1. Carl Claudy compares this process to a sculptor carving away unnecessary stone to disclose a statue that was present all along 1. Beyond individual self-improvement, the gavel functions as the Worshipful Master's emblem of authority, reminding him that the highest office in the lodge is exercised through the commonest tool and that he remains a brother among brethren 1.

The square stands as the premier implement of the builder, representing the single correct ninety-degree right angle necessary to construct a sound wall or cathedral 1. The plumb line, associated with the prophecy of Amos, guides how a Mason evaluates both his own conduct and that of others 2. Claudy notes that setting a plumb line in the midst of the people teaches judgment based on the specific circumstances and tools of the workman rather than an abstract standard applied from afar 2.

Among the various implements, Arthur Edward Waite identifies the compasses as perhaps the most spiritual of all the working tools, noting its presence throughout the degrees 3.
