Lost a razor blade

So I was fragging some Anthelia & Xenia the other day, and all of the sudden...my razor blade was no where to be seen.
4 of us sitting there, and none of us saw it fall.  It is a gold-colored blade stamped "titanium coated" that I got at Home Depot or Lowes, the box-cutter style.
So after we searched all the carpet and furniture, and everyone left, I proceeded to remove the light fixture, shut all the pumps and power heads off, and got my LED flashlight and began searching...and searching...
I moved rocks and corals all around.  Nothing.
Today I went in there after the DIY food meeting.  I used 1/2 of a kiddie fishing pole with a 1" x 1/2" x 1/4" magnet zip-tied on the end, and trolled all around the tank, everywhere I could.
NOTHING.
I am at a loss at this point.  I even dropped another razor blade in there several times to see where it might go.  They fall completely unpredictably.  It could be anywhere and it's totally freaking me out, especially since it's not my tank!!!
I might need some help at some point in the next couple days.  I have a feeling that the only solution to this problem is to take all the corals and rock out of the tank until I find it.
So unless anyone out there has any better ideas, I think that's what I'm going to have to do.  I'm not going to let a razor blade sit and rot away in this tank - no way.  But I think I'm going to need at least one extra set of hands.  I will probably do this first thing in the morning tomorrow (Sunday).
I'll frag you a piece of anything in the tank if you help.  The tank is in Grimes (Des Moines area)

 

Tim @ seascapes said he thought it might be OK. Said to watch the softies and if they start to have issues, dig it out.

 

Do you like my magnet-on-a-stick though?

 

I thought of that. I guess I won't have to dose Iron for my algae screen for a while, eh?

 

Thank you everyone for putting my mind at ease. I was totally stressing out about this. I guess it gives me a reason to stop in and check on everything a little more often this week.
