slick trick questions

[Hoytail Hunter]

1) What is the difference between the deadbolt bladelock and the alcatraz bladelock?

2) Has slick trick always had the one piece steel rhinoferrule that is "stronger than titanium" or is this a recent refinement? If recent, how do I tell the difference between the two? I don't want to end up buyingleft over stock that would be missing the upgrade.

Thanks

c'mon, one of you slick trick guys must know the answer to at least #2 right?
