Yes they can. HOWEVER you need to have a very light cut on the blade,
have cambered the blade so as to not leave any plane tracks.
Took a handtool class with Rob Cosman in Canada last summer. The
finish off his pieces from the LN 5 1/2 he used was perfect. If you
APPLY a finish, the difference becomes moot.
Just completed and ready to finish a pair of floating shelves, I
handplaned and scraped them for a bit, and then took a 1/4 sheet sander
to them to fix my own errors of not cambering my blade enough. The
amount of sanding was mere minutes total and I likely over did the time
necessary. With the planed/scrapped surfaces, there was no need to
sand out knicks or tearout from the planer. Just remove a couple of
raised ridges from a knicked planer knife.
