Tried this when I wanted a tool to help pick a tubular lock that was being difficult with the improvised stuff I was trying and which I didn't want to drill out. Of all the hardware stores and hobby shops I called, only one actually took me seriously and checked to be sure they didn't have it. All the rest falsely told me that lock picking was illegal and seemed to take offense.

Ended up buying some cheap shit off ebay that got the job done.
