Gil Hibben Tailwind Assisted Opening Pro Pocket Knife Imitation Abalone

I am a big fan of Gil Hibbon knifes I've sold many and my customers love them.I have bought and sold many,when it comes to the Pro Folder Tailwind I've had a lot of problems,the knife blade on many of them pops open on it's own.I tell everyone that the Tailwind assist is the best assist system their is and I still believe that.The Pro Folder is the only Tailwind knife I've had that problem with and I have sold many differant Tailwind assist knifes.When you get a Gil Hibbon Pro Folder that work properly it's a great knife.I can only give this knife two stars because I have four sitting in their boxes with rubber bands around them collecting dust.Thank you Daniel Voges.
