    • The present invention provides a removable shield attachment for hand-held digging tools which is mounted on the tool handle below the tool head so as to not interfere with gripping along the length of the handle. The shield generally comprises a mounting portion adapted to be mounted on the handle below the tool head, a shield portion extending laterally outwardly and upwardly from the mounting portion, and a slot positioned between the mounting portion and the shield portion adapted for passing a blade of the tool head therethrough. In use, the shield portion is positioned above the blade, thereby intercepting debris flying from the blade and towards the worker. The shield is particularly designed for digging tools having a slidably fit tool head that engages an outwardly tapered working end of the handle, with the shield being attached to the handle in the same manner as the tool head itself.
