Wide Angle Wednesday Presents "Odd Tools"

I was here. Paid for a service. Saw something that struck me as odd, and said "that's odd". No one heard me but an inner voice said, "take out your camera".
I have a good idea how the thumbnail tool is applied. The "absence and extreme" tool and the tuning fork type device are no doubt important to this service but were not used today.
I will share the nature of this service tomorrow or gladly congratulate anyone who nails it.
