Hot dog — it took Stanley to decide it needed one too.  The No. 9 was introduced
in 1870 and listed in their catalogs simply as “Block plane, 10 inches in
length, 2 inch cutter”  until the 1892 catalog where they waxed poetic about it
being for the Piano Forte Maker and Cabinet Maker and how the side handle with
slot and set screw included with every plane made it ideal for using on its side
on shooting boards.  The hot dog wasn’t pictured or mentioned before that.

Ditto on the LN 9 hot dog.  Mine is back in the plastic bag.  I don’t find that
it makes it much easier to use on shooting board. I am glad I got the side knob
though — much more useful.
