I have an older set of K18's (the ones with the black body and silver lever blade)
I have removed the grub screw that holds the "pin" in place that in turn attaches the blade to the body, but still cannot remove this pin.
Also is the reach adjustment screw diffeent on these as I cannot seem to get it to turn with a 2mm allen like I have on the rest. Maybe I have rounded it out somehow???

I have not had any problem with my newer K18 or Puro's in this regard.
Is there anything different that I should be aware of??

I am trying to replace the old levers with a set of Straitline's.
