Differences Between Tenacious Folders?

[numbersman]

Many of you know that here in Oz we have great difficulty importing any sort of half decent folder. In the course of researching my case for importing a Spyderco Manix 2, Lightweight, I was pretty surprised to find that the blue Tenacious is listed as a controlled knife, whereas the regular black Tenacious isn't. Can anyone think of any reason for the two to be different? The Customs boys, and girls, like to apply a robust flick test, which it would appear was passed by a black one and failed by a blue one. Is there any reason for this, or did they just get a slightly sloppier blue one, which happens occasionally. I mean, even Spyderco's quality control isn't perfect! Your thoughts?

Probably 2 different government drones inspected the respective knives. One drone could care less about knives, the other probably has a hard-on for "weapons."

Likely personal bias.
