"Dragonfly 2 Pin"---What does "Pin" signify?

[AJF]

This is probably so simple I'm gonna be embarrassed I asked, but here goes: on the Dragonfly 2 box (C28PBK2), the upper right corner of the label has "Dragonfly 2 Pin". What does "Pin" signify?

Thanks very much.

I think I threw out my Dragonfly box but I'm certain it's "Pln" for Plain Edge.

Thanks, Carrot. That's gotta be it.

I think it's pinned construction isn't it?

I'm pretty sure the Southfork box says "Phil Wilson Pin" on it.

PLN is shortened form for Plain Edge, as carrot said.
