Wire twister for soldering. I specifically designed this to twist diodes into coils when building hand wired keyboards. The twist allows you to slide the component onto another wire for safe keeping while you solder it in place. 

Required Parts: 
18 Gauge 1 -½ INCH brad nail (I trimmed the head off a brad nail and used that as the center post. You can also use a sturdy paper clip)
