No I didn't shoot my Hatamoto to fix the bladeplay.
I love this folder, but there was a little vertical bladeplay. I disassmbled it and put it back together. I tightened the pivot but there was still wobble. I even bent the liner further out; this helped but there was still vertical movement. My last option was to thicken the blade stop. I was looking for a metal sleeve that would fit over the blade stop. A .22 cal casing was perfect. I cut off a 4mm length from the shell and slid it over the blade stop. Voila! Its perfect with no blade play. You can probably use this for other folders that develop blade play.
