Horolovar Mainspring Let Down Tool.

Mainspring let down tool is used to safely unwind your clock's powerful mainspring, so that you may disassemble the movement for proper cleaning and lubrication without injuring yourself, and causing extensive damage to the movement. This tool is designed to fit over your clock's key, and work for almost all keys on the market. There is one size that will fit most keys. This tool is built to last, with solid cherry hardwood handles, and thick, high quality steel. 

To use, insert your key into the slot in the tool. Then insert the key into the winding arbor as shown in the second picture. Firmly grasp the handle, and turn the tool counter-clockwise just a hair so that pressure is removed from the ratchet wheel and click*. Lift the click away from the ratchet wheel, then slightly release the pressure of your grip on the tool to allow the tool to slowly rotate in your hand until the mainspring has fully unwound.
