[5] Learning lock picking - 1 month experience

Fairly hard transparent lock.
It has 5 normal pins and 2 of them overset very easily.
Moreover it has a small key way (I believe this key shape is called Yale?), which makes it difficult for a beginner.
In this video I was training with top of the key tensioning because I had another new lock that needed top of the key tensioning and I wasn't good at it, so I needed more training.
That tensioning tool is not the right one for top of the key tensioning, but I still didn't have my proper tensioning tools at the time.
