Introduction to Impressioning ~ Part 1

This is part 1 of 2 parts on an introduction to impressioning pin tumblers. It's really aimed at someone who already has an understanding of points such as what a shearline is or how binding pins work. I'm definitely no expert on this, so if anyone has any of their own additions or alternatives, that would be very cool to help anyone get going. What you see here is just my own spin on impressioning. Part 2 can be found here:    • Introduction to Impressioning ~ Part 2
