This design is a very unique scissor opening (Swinglock)folder, which when the blade is fully open and locked in place is almost a fixed blade knife. The handle is nicely contoured for a comfortable grip. Opening is accomplished by lighting pressing down and outward at the rear indentation in the backspacer, which releases the locking pin and allows one side of the handle and the blade to rotate down then forward until the blade locks in the forward position. The other side of the handle continues to rotate back until it locks in place. Closing requires the same slight thumb pressure at the indentation to release the locking pin, then the one side of the handle is rotated back and around, catching the blade and aligning both with the other side of the handle in a locked closed position. Sounds complicated but actually works quite smoothly after a few minutes practice. Really neat and IMHO the most stable of 'lockers' since it is almost impossible to inadvertently open when held or stressed.
