Introducing the Double Helix! This is the FIRST double action flipper! Available and ready to ship for $800.
The Double Helix has an open spine! The kicker spring and release mechanism are all housed inside the front handle. The screw above the pivot slides forward to open in automatic mode. This screw can also be tightened up to lock out the auto function. The Double Helix has the smooth bearing pivot I use in my folders and is a frame-lock design. It's a big folder with a .150" thick and 4.5" long blade.
