The copper is all battery and switch, 2/CR2 3V, which tends to operate between 5.25 and 6.5. The switch is unique, and isn't always reliable on the first try, but hasn't failed entirely yet. The brass body is just plain tough brass tube with large brass ends. It cleans very nicely with polish.
I didn't like the battery life, the long length of the switch/connector, no off mechanism. Frankly the switch connector could be finished a bit cleaner.
It does hammer out the volts, hold up to huge abuse, and is mostly reliable.
