Bolt cutters
We have to admit, when you are at the store buying bolt cutters you always look suspicious no matter what. Even if you had good intentions in your mind, buying bolt cutters is never a casual experience. A lot of eyebrows are raised if you look like a sketchy character and questions will be asked.
These bolt cutters are actually a test for the consumer. Only someone who is not a criminal would have difficulty cutting the chain and getting the bolt cutters, a real thief would do it in no time. So based on how fast you are, they decide whether or not they let you buy them in the end.
