What to do if you want to solder two cables together? For this you would need 4 hands. Two hold the two cables, one the solder and the 4 hand the soldering iron. With this tool, I can clamp both ends of the cable and have therefore both hands free for soldering. In very small cables I can look much more closely because my poor eyes through a magnifying glass. For me, a great helper when digitizing my old locomotives from Märklin.
