Treestump has chest hair? I never noticed any of the elves with any body hair whatsoever. Where is that shown?
As for Cutter's necklace-- Searcher and the Sword shows that it's bendable and doesn't meet at the back, but can just be bent and taken off. Which begs two questions:
1. Why doesn't the back ever slip around to the front? My necklaces do that all the time!
2. If he can take it off and bend it so easy, why didn't he just take it off and bend it into a hook to retrieve his sword during the Trial of Head in Book 1?
(you guys can call Mr. Pini a dork if you want to-- I just don't feel I know him well enough yet. He'd have to hang around here more)
