Really good video explaining spool and serrated pins

[Squelchtone]

Here's a great little video I found on youtube explaining how security pins work inside locks. Every beginner should watch this, you'll immediately understand the concept.

Great oversized keyway and pins and explains to me exactly what is happening when a pin is false set. Excellent resource for a newby, thank you.
