Slim line lock picks can be purchased individually so you can build your own tool kit. We also have a number of Slim Line complete lock picking sets available. Slim line lock picks are primarily designed for smaller keyways found mostly in locks that were made in Europe or Japan. The Slim Line locks picks will also work on all USA made locks. The benefit of purchasing lock picks individually is that you can buy only what you need without going overboard. We all know that certain tools get used more than others, in fact, many locksmiths prefer to use the same type of picks over and over again rather than using a wide variety. By purchasing only what you need, when you need it, you'll save money and have a lock picking kit of your own custom design! Once your slim line tool kit is complete all you'll need to do to maintain it is pick up a few more lock picks as you need them.
