Second question why are they called "hook and loop" sanders? I don't
understand this name, don't see anything on it that looks like a hook or a
loop.

Velcro is a trademarked name - similar examples of terminology would be
Kleenex vs. facial tissue and Xerox vs. photocopy. Hook and loop is the
mechanism that was invented with Velcro. Stiff plastic hooks on one part
grab onto the fuzzy loops of the other.

Just one word of warning: Don't overheat the sanding pad by using too
fine a grit to remove coarse surface imperfections or by pressing too
hard against the surface - you'll melt the plastic hooks and they'll no
longer grab the loops. At that point you'll have to replace the hook pad
to get it to stop Frisbee-ing (yet another example of trademark vs.
terminology) the sanding disks across the shop.
