I am trying to swap out my Leonardo Momento Zero Nib. The replacement nib I bought from the same seller is a complete collar + feed + nib unit in one. It is clearly screw type from the thread. I have tried like hell to screw it out but it seems stuck. I also very gently tried tugging as my Grande had the tug type, but I know the Leonardo Reg Momento Zero’s newer ones are screw in ( reinforced by fact that the replacement t I bought is also screw in) . Mine is the Positano with the number 1296 so may well be an older ‘ tug’ type.
a) would anyone know how to unscrew a stuck nib?
anyway to tell if my particular pen has screw in or friction. Would be good to know before I applied force pulling.
c) any other suggestions.
many thanks in advance.
