Comb picks are highly effective at bypassing a large number of lower security locks. Comb picks work by pushing the entire pin stack above the sheer line.
YES, both the bottom and top pins go above the sheer line in the lock. Then just turn the Comb pick like a key.
The most vulnerable grouping of locks are 4 and 5 pin locks, and that is what the COMB .45 is designed for.
Sparrows lock picks have even worked the teeth in a way that lets them work for the MASTER 140, MASTER 150, MASTER 40mm, MASTER 50mm They will even open an ABUS 5 pin 55/50. If the lock says 40mm or 50mm on the bottom, the odds are good that you can open it with Comb picks.
