Gold Point atomic lock hook a full-wave 20, using all stainless steel refined, so-called wave waves hook is designed to mimic the key tooth wave shape, with a lock according to the marbles in the differential curve to design.
Instructions:
Jitter or wavy sliding hook when the speed should be moderate, with a mean change in a second variable advance. In case of resistance, then analyze and then continue to analyze the theory is: When the side column into the tumbler marbles gap, hook a slight wave of resistance exist, whether it is on top of the spring force marbles, marbles or waves will hook under the pressure will have resistance, then it should pay attention, if you feel little resistance, began to look under the pressure waves or by lifting the hook, repeat again and to be tilted about a little slight movement back and forth on.
