A year or so back, there was a tip (in FWW) by Jimmy Carter on
sharpening jointer blades in-situ. I did not pay much attention at the
time, as I did not own a jointer, I have now acquired an old one with
3 sets of blades, 1 set is OK, just, but the other 2 are worse for
wear.

What was his technique?

A sharpening service.




I recall several FWW issues w/ Jimmy in them in various forms, but
nothing sharpening jointer knives...

I'll concur w/ the other posters--unless they only need a very light
touch up, unless you can set up a good jig to ensure maintaining a
completely straight edge and have a slow speed water wheel, grinding
them yourself is, while not impossible, error prone at best--and that's
assuming they're steel, not carbide.

Best to find a good sharpening service--but be sure they know what
they're doing--I once took a set to a fool who ground them by hand into
a nice set of hollow paint scrapers...

There are, of course, for larger jointers (typically 8" and up) "on the
machine" sharpening setups--the older 8" and larger Delta's for one have
drilled/tapped holes in the outfeed bed for mounting the carriage
mechanism. I don't know whether the new Deltas have that as a
feature/option or not?
