ROUGH RYDER AO TRAPPER

Just seen these at SMKW and am trying to figure out the action on them.
Are they assisted open?

Looks like a 'flipper'. Just slight pressure on the tab and the blade swings open and locks. Likely has bearings at the pivot to give it this action.
Flippers i have swing open almost as fast as an auto.

That's what I was thinking but wasn't sure. Thanks
