They were little old pin tumbler suitcase locks, from before TSA took away all semblance of security from them. Had to use a half diamond and tension wrench made from a bobby pin (hair pin) to pick them because they were so tiny. I also used them for some warded locks like the Sterling Jr. locks.
I used wiper inserts because the blanks are very difficult to find. To use them, use a Sharpie to ink the edges, and then put the insert into the keyway on the pin side. Use a turning tool to bind the pins and wiggle the insert side to side. Remove the turning tool, then the insert. Look at the edge of the insert for places where the pins wore off the ink. File there using needle files.
Takes some practice, but it does work.

Just when you finally think you have learned it all, that is when you learn that you don't know anything yet.
