What knife does Reacher use in Gone Tomorrow?

The character Jack Reacher uses a knife in the book by Lee Child, "Gone Tomorrow."  So what knife did Reacher use in Gone Tomorrow?  He used a Benchmade 3300.  You can google it.  It looks like a very nice knife.  It is a double action, out-the-front (OTF) knife.  I did not know such knives existed.  A double action means there are two springs.  One spring will extend the blade, the other spring will retract the blade.  That looks very appealing.  Most assisted opening OTF knives require a manual retraction, where you yank some lever back to retract the blade.  The problem is that this knife sells for $400 to $500, which I think is prohibitively expensive for the average consumer.

At the time of this writing there are videos on YouTube that demonstrate this knife.
