Came across it on Amazon while looking for a completely different type of lock.

This was my first (and only successfully opened so far) disc detainer lock. Also used Sparrows' tool to open it. the two prongs on the pick are long enough that they reach the first 2 discs though, so after inserting it, I had to back it out ever so slightly so they were only on the first disc.
