An accessory device for fastener-driving tools such as nail and staple guns is provided. The device serves as a positioning guide for the tool and is designed to provide sufficient spacing and orientation between the fastener-driving tool and the target constructio n material. The device can be integrated into the beady of the fastener-driving tool, manufactured as an attachment or manufactured as a separate tool. It prevents impact marring at the visible surface of the construction material by redirecting the force of the blow to a non- visible surface on the assembled construction material. Furthermore it increases speed and ease of movement for the user by serving as a guide for stability and ease of alignment. The device changes the impact point between the driving tool and the construction material, broadens the area of impact and protects the top edge of a tongue and groove construction material from impa ct damage.
