Rounded? Or cambered? It's not unusual to camber, or slightly round the
corners of the plane blade, so as not to leave 'plane tracks'.

Scrub/Jack plane - cambered - sure. #8 joiner? Don't think so.

Christopher Schwarz says to camber a jointer, as does Jeff Gorman. I haven't
done it yet, but intend to. :-)

I would say that Lie Nielsen concurs since Schearz is on one of their DVD's
and that's one place he said to do it.


A #7 & #8 are primarily used for getting the edge a board flat and
straight- for edge joining two boards - hence "joiner/jointer" name.
Resulting surface doesn't have to be square to the face of the
boards - IF the two boards are against each other and "joined"
at the same time.

If there's a slight curve / camber in the iron it should produce
a slight concave surface. That means not much contact between
the two boards being edge glued together - and a very weak joint.

Am I missing something?
