Hi Mark,
If it is arguable that a flute is a tool? ... And I believe its is arguable, then my 1st example should answer your question.
If we will be sticking with the strictest meaning of a tool, then the second example of Ivory sewing needles should satisfy your question.
In 2012, researchers discovered the worlds oldest musical instruments, 42,00043,000 years old. The find was identified by Professor Nick Conard, the Tuebingen University researcher who was also the lead excavator of the previous record holder, also found in a nearby area in 2009. The instruments are bone flutes, one of which was fashioned from mammoth ivory, the other from a birds bone. They were found in the Geissenkloesterle Cave in the Upper Danube region of southern Germany. Based upon the finds from this cave and others in and around the region, it is thought that humans entered the area 39,00040,000 years ago, just before an extremely cold climatic period. Professor Conard believes that the artifacts collected from the area indicate that the area served as a corridor for the flow of technological innovations into Europe at the time. Music could have been used for recreation or religious ritual and could have been part of a suite of behaviors that allowed early humans to out-compete Neanderthal man.Some scientists believe that the ability to play music goes back even further. Professor Chris Stringer, a human origins researcher at the Natural History Museum in London who worked on instruments discovered in the Hohle Fels cavern in southwest Germany, believes that humans may even have possessed the trappings of advanced cultural creativity as far back as Africa over 50,000 years ago or even earlier.
The oldest dated bone and ivory sowing needles with eyelets were found at a group of more than 20 sites along the Don River near the villages of Kostenki and Borshevo (250 miles south of Moscow). Most of the stone used for artefact construction was imported from between 60 miles and 100 miles away
The main display room in the Kostenki Museum shows a dig partially excavated, with the remains of mammoths strewn across the floor.
Approx age:30,000 - 40,000 BP
Location: Kostenki, Russia
I will be sad to see these threads disappear ... But I understand your frustration.
Thanks for you're generous nature Mark and I certainly appreciate your efforts to keep Ivory free of undue legislative bans and available to craftsman.
