Thanks for all the support and sympathy.
I took everyone's advice and had some tea and frosted some Christmas cookies. The Diane and I looked together.
Still no luck.
So I slept and rested and tried again today! Still no luck.

I can honestly say she and I have searched everything in and around the house. There's not a trace of it.
I don't have another blade so I can't make him a replacement just yet, but I will show him the picture and promise another one just so soon as I can get another blade.
That's about the best I can do and I've made my piece with it.

Thanks again for helping me vent.
