Side Opening Trap Door Folder #3

Overview

This folder by Phil Boguszewski features a hand rub satin finished blade with single thumbstud. The handle has a stainless steel frame with checker milled folding door, tip up or down reversible titanium clip. Excellent condition. This knife is #3. 

It can be opened very quickly with a back and forth wrist motion. Its hard to explain, but if you hold the knife closed, then with your thumb push the trap door open while swinging it back towards you, then swing the knife back forward and the blade with fly out and the trap door will close behind it. Takes a few trys to get it down, but it is a very cool design.
