Wasn't sure where to put this topic, Waterman or Repairs, so I just rolled the dice. I have a 'Palladium/Silvertone' trim Waterman Carene with a very wet, juicy M nib. Can these types of nibs (inlaid) be successfully re-ground? And if so, any particular nibmeister recommendations for this sort of job? I want it taken down to F or even EF. Thanks.
