Fuji Kogyo Universal nail clamp

You can easily hit a nail in a narrow space without bending it.
For carpenters, you can hit the nails without bending when making an embedded box in a place that is out of reach such as a sword, and for electrical work, in a narrow place.
Since the tip is a magnet type, especially when hitting a nail in a narrow place, even when the mallet does not swing, you can hit it reliably even if you hit it upward, downward, or diagonally.
