⚙️ This tool is known as a portable external concrete vibrator or handheld formwork vibrator. Unlike an internal poker vibrator, it is not inserted directly into the mix; it is pressed against the formwork to transmit vibration, helping fresh concrete flow better, release trapped air, and settle around the reinforcement. 🏗️ It is especially useful for small structures such as tie beams, curbs, lintels, low walls, thin columns, and elements where an internal vibrator has limited access.
