What knife has a rolling mechanism on the back?

[Oreyeon]

I remember seeing a knife in the Kershaw Forums when it was alive. A new model that was soon to come out. On the spine of the knife, the spring assist mechanism, was like a rolling stud, you rolled it back or forward, and as it went down into the spine, the blade would pop. What knife is this? Can anyone provide me links? Greatly appreciated. Thank you.

I don't recall such a knife. The Cyclone has an on/off switch on the spine but it didn't open the blade. The switch just activated or de activated the torsion bar. There may have also been a Hawk RAM II or III concept that had the lock release on the spine, but, no speedsafe or anything like that.

Edit: I reread you post and it sounds like you are describing the OD-1, but, that knife isn't speedsafe either.

He is talking about the OD-1, however the OD-1 is not spring assisted. It just "feels" like it is because it pops out so fast! Someone please post those pictures, I can't search for them.

The od-1 sounds right.

There's a video with a close up of it in action, so you should be able to tell from this.

Yep, it's the OD-1. Thank you tons.
