Scraper plane. A #80 (cheap Stanley) or a #112 (Lee Valley /
Lie-Nielsen, not so cheap). Most people have never used a scraper
plane, and they're missing out.

Block plane. He's got one already. Get him the Lee Valley low-angle
adjustable-mouth block plane and show him what he's been missing.
Their shoulder plane looks good too.

If he isn't big on hand tool woodworking already, almost anything
from Lie-Nielsen would be good. The quality is enough to convert
someone to the handtool side, and the stuff pretty much looks like
works of art.

If he already has & uses handplanes, then a scraper plane is an
excellent idea...it's one of those revelation type tools, the
first time you use it.

Try to find a tin for all the pens and rubbers.

This is English English. He means erasers.
