Sparrows Master Switch
The Master Switch
This is a great by-pass tool For Master padlocks #1,#2,#3,#4.
By inserting both switch's deep into the key way of the lock you are able to open the padlock.
With the assistance of some padlock shims you can even open Master padlocks #5,#6.
The Master Switch is just a fun tool to use.
You might be just as fast to pick the lock open but their is something to exposing a built in weakness and using a bypass tool
