Probably the modeler's most useful and valuable tool ever!

As it is self-locking, it will hold onto anything without your fingers tiring from clutching onto a tweezer for long times.  Ideal for holding onto small items like N and HO-scale figures being painted.  Also suitable to hold onto wires that you want out of the way while installing a DCC decoder in your locomotive.  Also suitable for people that do beadwork and embroidery.
