Improved tool with reusable holder, including a U-shaped holder (1) with elongate ends, a tab (4), nail-holes (5) for the insertion of nails and at least three circular holes (6) with a peripheral stepped portion (7); and a disposable part (2) with a concave shape (3) that matches that of the holder, with an upper recess (8) corresponding to the tab (4), and at least three flared protrusions (9) positioned in line with the circular holes (6) in the holder (1). The flared protrusions (10) are in the form of vertically open studs with a wider part that engages in the stepped portion (7) of the circular holes (6). To secure the attachment, a plastic screw (10) is inserted in each flared protrusion (9), causing the flared protrusion (9) and the wider part thereof to expand over the stepped portion (7) of the circular hole in which it is inserted. |
