Thank you everyone.  I have done the one-click order for the 750x.
  Long ago, in another lifetime, I had access to the type of sharpener that
mounts on a workbench next to a grinder.  It worked OK with careful use.
 The bench grinder that I have now does not seem to be stable enough for
that type.
   I have had some success with free hand sharpening, and have great
respect for those who are skilled at it.  Now that I have only one good
eye, those 3-D, multiple angle situations are very difficult.   :-(

Stay sharp,
Larry A.
