<p>The Digging Multi-Tool is a general-purpose 'go to' compound hand shovel with a socket handle offset from the center attached to the spade at a non-right angle in the plane of the pan, for easier digging, cutting and moving of materials through the advantages of torque and geometry. The spade has a corrugated safety cleat to reduce risk of injury. Various edges may be sharpened appropriate to intended cutting uses. The socket and associated exchangeable hafts have a Reuleaux (rounded) triangle cross-section to provide better control and feedback to the user and more options for applying force and reach.</p> |
