Perfect blade centering is BS when it comes to functionality.
I bought a Pkal from AGRussell and got to pick from two. I chose the one with the best action that was not the display model even though it was a little off center. I purposely picked an off center blade. I've waved it open many many times over the past 6 years. I practice while walking the dog. Learning the wave I've thrown it across the room and dropped it on concrete The blade centering is still rock solid - off center
