12 is probably used in clock wheel repair work; I'm assuming that there
are holes in the pointed ends of the rods. The hook is for securing
the wheel in one position while work is being done at one part of the
wheel.

I sent an email to the owner of it asking if there are holes in the pointed
rods but haven't heard back yet.

Others have guessed apple corer and chemist scoop for number 11, neither of
these is correct although the word scoop is part of the right answer.
